• Hadronic Z decay events generated on the Z pole (sqrt(s) = 91.2 GeV)

The charged particle multiplicity distribution of hadronic Z decays, as measured on the peak of the Z resonance using the ALEPH detector at LEP. The unfolding procedure was model independent, and the distribution was found to have a mean of 20.85 +- 0.24, Comparison with lower energy data supports the KNO scaling hypothesis. The shape of the multiplicity distribution is well described by a log-normal distribution, as predicted from a cascading model for multi-particle production.

• e^+e^-\to jets with \pi and \eta decays turned off.

Earlier measurements at LEP of isolated hard photons in hadronic Z decays, attributed to radiation from primary quark pairs, have been extended in the ALEPH experiment to include hard photon production inside hadron jets. Events are selected where all particles combine democratically to form hadron jets, one of which contains a photon with a fractional energy z > 0.7. After statistical subtraction of non-prompt photons, the quark-to-photon fragmentation function, D(z), is extracted directly from the measured 2-jet rate.

Measurement of the b-quark fragmentation function by ALEPH using LEP 1 data. The fragmentation function for both weakly decaying and leading b-quarks has been determined. The data used for the plots has been renormalised to give a differential distribution rather than the bin-by-bin average in HEPDATA.

• Inelastic events (non-diffractive and inelastic diffractive).

Measurements of cross-sections of inelastic and diffractive processes in proton-proton collisions at \sqrt{s} = 900, 2760 and 7000 GeV. The fractions of diffractive processes in inelastic collisions were determined from a study of gaps in charged particle pseudorapidity distributions. Single-diffractive events are selected with M_{X} < 200\;\GeV/c^2 and double-diffractive events defined as NSD events with \Delta\eta > 3. To measure the inelastic cross-section, beam properties were determined with van der Meer scans using a simulation of diffraction adjusted to data. Note that these are experimental approximations to theoretical concepts -- it is not totally clear whether the data point values are model-independent.

The underlying event measurements with the ATLAS detector at the LHC at the center of mass energies of 900 GeV and 7 TeV. The observables sensitive to the underlying event, i.e the charged particle density and charged pT sum, as well as their standard deviations and the average pT, are measured as functions of the leading track. A track pT cut of 500 MeV is applied for most observables, but the main profile plots are also shown for a lower track cut of 100 MeV, which includes much more of the soft cross-section. The angular distribution of the charged tracks with respect to the leading track is also studied, as are the correlation between mean transverse momentum and charged particle multiplicity, and the `plateau' height as a function of the leading track |\eta|.

• QCD events at 7 TeV

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton--proton collisions at a centre-of-mass energy of \sqrt{s} = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb^-1. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The b\bar{b}-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m_{jj} < 760\;GeV, the azimuthal angle difference between the two jets and the angular variable \chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG+Pythia6. MC@NLO+Herwig shows good agreement with the measured b\bar{b}-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.

The production of Kshort and Lambda hadrons is studied in inelastic pp collisions at sqrt(s) = 0.9 and 7 TeV collected with the ATLAS detector at the LHC using a minimum-bias trigger. The observed distributions of transverse momentum, rapidity, and multiplicity are corrected to hadron level in a model-independent way within well defined phase-space regions. The distribution of the production ratio of Lambdabar to Lambda baryons is also measured. The results are compared with various Monte Carlo simulation models. Although most of these models agree with data to within 15% in the Kshort distributions, substantial disagreements with data are found in the Lambda distributions of transverse momentum.

A measurement of the jet activity in rapidity intervals bounded by a dijet system. The fraction of events passing a veto requirement are shown as a function of both the rapidity interval size and the average transverse momentum of the dijet system. The average number of jets above the veto threshold are also shown as a function of the same variables. There are two possible selection criteria applied to data. Either the two highest transverse momentum jets or the jets most forward and backward in rapidity are taken to define the dijet system, where the veto threhsold is 20GeV. Additionally for the latter selection an alternative veto transverse momentum threshold which is equal to the average transverse momentum is applied. Jet selections are based on anti-kt with R=0.6, p_\perp>20 GeV and |y|<4.4.

• Minimum bias inelastic pp collision at 7 TeV including diffractive component and overall cross section.

Pseudorapidity gap distributions in proton-proton collisions at sqrt(s) = 7 TeV are studied using a minimum bias data sample with an integrated luminosity of 7.1 inverse microbarns. Cross sections are measured differentially in terms of Delta eta F, the larger of the pseudorapidity regions extending to the limits of the ATLAS sensitivity, at eta = +/- 4.9, in which no final state particles are produced above a transverse momentum threshold p_T Cut. The measurements span the region 0 < Delta eta F < 8 for 200 < p_T Cut < 800 MeV. At small Delta eta F, the data test the reliability of hadronisation models in describing rapidity and transverse momentum fluctuations in final state particle production. The measurements at larger gap sizes are dominated by contributions from the single diffractive dissociation process (pp -> Xp), enhanced by double dissociation (pp -> XY) where the invariant mass of the lighter of the two dissociation systems satisfies M_Y <~ 7 GeV. The resulting cross section is d sigma / d Delta eta F ~ 1 mb for Delta eta F >~ 3. The large rapidity gap data are used to constrain the value of the pomeron intercept appropriate to triple Regge models of soft diffraction. The cross section integrated over all gap sizes is compared with other LHC inelastic cross section measurements.

• Soft-QCD proton-proton interactions (including diffraction) at 900 GeV or 7 TeV. Generated events should include an average lifetime cut of ctau < 10mm

Two-particle angular correlations are measured in proton-proton collisions at \sqrt(s)=900 GeV and 7 TeV. Correlations are determined for charged particles with \pT > 100 MeV and |\eta| < 2.5. A complicated function of both pseudorapidity and azimuth is observed. Results are obtained from an inclusive sample of events (900 GeV and 7 TeV), as well as a sample satisfying n_{ch} \ge 20 (7 TeV only).

• pp QCD events at 7 TeV

In this analysis, the assumption that the internal substructure of jets generated by QCD radiation is well understood is tested on an inclusive sample of jets recorded with the ATLAS detector in 2010, which corresponds to 35 pb^{-1} of pp collisions delivered by the LHC at \sqrt{s} = 7 TeV. Jet invariant mass, k_{t} splitting scales and N-subjettiness variables are presented for anti-k_{t} R = 1.0 jets and Cambridge-Aachen R = 1.2 jets. Jet invariant-mass spectra for Cambridge-Aachen R = 1.2 jets after a splitting and filtering procedure are also presented.

A measurement of the additional jet activity in dileptonic ttbar events. The fraction of events passing a veto requirement are shown as a function the veto scale for four central rapidity intervals. Two veto definitions are used: events are vetoed if they contain an additional jet in the rapidity interval with transverse momentum above a threshold, or alternatively, if the scalar transverse momentum sum of all additional jets in the rapidity interval is above a threshold.

Distributions of the charged-particle multiplicity, the scalar sum of the transverse momentum of charged particles, and the average charged-particle pT are measured as functions of \pT^\text{jet} in regions transverse to and opposite the leading jet for 4 \GeV < \pT^\text{jet} < 100 \GeV.

But for simplification of its usage it only requires events with the electronic final state (muonic final state will be ignored).

The Z pT, in a fully-factorised picture, is generated by the momentum balance against initial state radiation (ISR) and the primordial/intrinsic pT of the Z's parent partons in the incoming hadrons. The Z pT is important in generator tuning to fix the interplay of ISR and multi-parton interactions (MPI) ingenerating `underlying event' activity. This analysis is subject to ambiguities in the experimental Z pT definition, since the Rivet implementation reconstructs the Z momentum from the dilepton pair with finite cones for QED bremstrahlung summation, rather than non-portable direct use of the (sometimes absent) Z in the event record.

The original CDF underlying event analysis, based on decomposing each event into a transverse structure with ``toward'', ``away'' and ``transverse'' regions defined relative to the azimuthal direction of the leading jet in the event. Since the toward region is by definition dominated by the hard process, as is the away region by momentum balance in the matrix element, the transverse region is most sensitive to multi-parton interactions. The transverse regions occupy |\phi| \in [60\degree, 120\degree] for |\eta| < 1.

A study of p\bar{p} collisions at sqrt(s) = 1800 and 630 GeV collected using a minimum bias trigger in which the data set is divided into two classes corresponding to `soft' and `hard' interactions. For each subsample, the analysis includes measurements of the multiplicity, transverse momentum (pT) spectra, and the average pT and event-by-event pT dispersion as a function of multiplicity. A comparison of results shows distinct differences in the behavior of the two samples as a function of the center of mass energy. The properties of the soft sample are invariant as a function of c.m. energy. It should be noticed that minimum bias tunings of PYTHIA made by ATLAS in early 2010, which used this among all other available data from CDF and from ATLAS at 900~GeV and 7~TeV, found an unavoidable tension between this data and the rest. Accordingly, this data was excluded from the fits. Whether this reflects a problem with this dataset or with the PYTHIA MPI model is a judgement for users to make!

• QCD events at sqrt(s) = 630 & 1800 GeV. Several pTmin cutoffs are probably required to fill the profile histograms, e.g. 0 (min bias), 30, 90, 150 GeV at 1800 GeV, and 0 (min bias), 20, 90, 150 GeV at 630 GeV.

This analysis studies the underlying event via transverse cones of R = 0.7 at 90 degrees in \phi relative to the leading (highest E) jet, at sqrt(s) = 630 and 1800 GeV. This is similar to the 2001 CDF UE analysis, except that cones, rather than the whole central \eta range are used. The transverse cones are categorised as TransMIN and TransMAX on an event-by-event basis, to give greater sensitivity to the UE component. `Swiss Cheese' distributions, where cones around the leading n jets are excluded from the distributions, are also included for n = 2, 3. This analysis is useful for constraining the energy evolution of the underlying event, since it performs the same analyses at two distinct CoM energies. WARNING! The pT plots are normalised to raw number of events. The min bias data have not been reproduced by MC, and are not recommended for tuning.

CDF Run II measurement of inclusive jet cross sections at a p-pbar collision energy of 1.96~TeV. Jets are reconstructed in the central part of the detector (|y|<2.1) using the kT algorithm with an R parameter of 0.7. The minimum jet pT considered is 54~GeV, with a maximum around 700~GeV. The inclusive jet pT is plotted in bins of rapidity |y|<0.1, 0.1<|y|<0.7, 0.7<|y|<1.1, 1.1<|y|<1.6 and 1.6<|y|<2.1.

A measurement of the underlying event activity using Drell-Yan events using muonic final state. The production of charged particles with pseudorapidity |\eta| < 2 and transverse momentum p_\perp > 0.5\,\GeV/c is studied in towards, transverse and away region w.r.t. to the direction of di-muon system. The UE activity is measured in terms of of a particle density and an energy density. The particle density is computed as the average number of primary charged particles per unit pseudorapidity and per unit azimuth. The energy density is expressed in terms of the average of the scalar sum of the transverse momenta of primary charged particles per unit pseudorapidity and azimuth. The ratio of the energy and particle density is also reported in 3 regions. UE activity is studied as a function of invariant mass of muon pair (M_{\mu\mu}) by limiting the ISR contribution by requiring transverse momentum of muon pair p_\perp(\mu\mu) < 5\,\GeV/c. The p_\perp(\mu\mu) dependence is studied for the events having M_{\mu\mu} in window of 81--101 GeV/c. The normalized charged particle multiplicity and p_\perp spectrum of the charged particles in three regions also been reported for events having M_{\mu\mu} in window of 81--101 GeV/c. Multiplicity and p_\perp spectra in the transverse region are also reported, for events having p_\perp(\mu\mu) < 5\,\GeV/c.

• Inelastic events (non-diffractive and inelastic diffractive).

The inelastic cross-section is measured through two independent methods based on information from (i) forward calorimetry (for pseudorapidity 3 < |\eta| < 5), in collisions where at least one proton loses more than \xi > 5 \cdot 10^{-6} of its longitudinal momentum, and (ii) the central tracker (|\eta| < 2.4), in collisions containing an interaction vertex with more than 1, 2, or 3 tracks with p_\perp > 200 MeV/c.

• Run MC generators with Z decaying to leptonic modes + jets and photon + jets at 7 TeV centre-of-mass energy.

Rapidity distributions are presented for events containing either a Z boson or a photon in association with a single jet in proton-proton collisions produced at the CERN LHC. The data, collected with the CMS detector at \sqrt{s} = 7 TeV, correspond to an integrated luminosity of 5.0/fb. The individual rapidity distributions of the boson and the jet are consistent within 5\% with expectations from perturbative QCD. However, QCD predictions for the sum and the difference in rapidities of the two final-state objects show significant discrepancies with CMS data. In particular, next-to-leading-order QCD calculations, and two Monte Carlo event generators using different methods to merge matrix-element partons with evolved parton showers, appear inconsistent with the data as well as with each other.

First measurements at a hadron collider of differential cross sections for Z (\to \mu\mu)+jet+X production in \Delta\phi(Z, j), |\Delta y(Z, j)| and |y_\mathrm{boost}(Z, j)|. Vector boson production in association with jets is an excellent probe of QCD and constitutes the main background to many small cross section processes, such as associated Higgs production. These measurements are crucial tests of the predictions of perturbative QCD and current event generators, which have varied success in describing the data. Using these measurements as inputs in tuning event generators will increase the experimental sensitivity to rare signals.

Direct photon pair production cross sections are measured using 4.2 fb^{-1} of data. They are binned in diphoton mass, the transverse momentum of the diphoton system, the azimuthal angle between the photons, and the polar scattering angle of the photons. Also available are double differential cross sections considering the last three kinematic variables in three diphoton mass bins. Note, the numbers in version 1 of the arXiv preprint were missing the dM normalisation in the double differential cross sections. This has been reported to and fixed by the authors in v2 and the journal submission. HepData as well as the Rivet analysis have also been updated.

Measurements of transverse energy flow for neutral current deep- inelastic scattering events produced in positron-proton collisions at HERA.

The transverse energy flow is measured in the hadronic centre of mass frame and is studied as a function of Q^2, x, W and pseudorapidity. The behaviour of the mean transverse energy in the central pseudorapidity region and an interval corresponding to the photon fragmentation region are analysed as a function of Q^2 and W. This analysis is useful for exploring the effect of photon PDFs and for tuning models of parton evolution and treatment of fragmentation and the proton remnant in DIS.

The energy flow created in pp collisions at 7 TeV within the fiducial pseudorapidity range of the LHCb detector (1.9 < \eta < 4.9) is measured for inclusive minimum bias interactions, hard scattering processes and events with enhanced or suppressed diffractive contribution. Plots for these four event classes are shown separately for all and charged only final state particles, respectively. The total energy flow is measured by combining the charged energy flow and a data-constrained MC estimate of the neutral component. For the two highest eta bins the data-constrained measurements of the neutral energy were extrapolated from the more central region as the LHCb electromagnetic calorimeter has no detection coverage in that phase space domain.

The differential cross-sections are measured in bins of hadron transverse momentum (p_T) and rapidity (y) with respect to the beam axis in the region 0 < p_T < 8 GeV/c and 2.0 < y < 4.5, where p_T and y are measured in the proton--proton CM frame. In this analysis code, it is assumed that the event coordinate system is in the proton--proton CM frame with the z-axis corresponding to the proton--proton collision axis (as usual). Contributions of charm hadrons from the decays of b-hadrons and other particles with comparably large mean lifetimes have been removed in the measurement. In this analysis code, this is implemented by counting only charm hadrons that do not have an ancestor that contains a b quark.

The inclusive production rate of neutral pions has been measured by LHCf experiment during \sqrt{s}=7 TeV pp collision operation in early 2010. In order to ensure good event reconstruction efficiency, the range of the \pi^0 rapidity and p_\perp are limited to 8.9 < y < 11.0 and p_\perp < 0.6 GeV, respectively.

• ppbar events. Non-single diffractive events need to be switched on. The trigger implementation is the same as in UA5_1989_S1926373. Important: Only the correlation strengths with symmetric eta bins should be used for tuning.

Data on two-particle pseudorapidity and multiplicity correlations of charged particles for non single-diffractive \bar{p}p collisions at c.m. energies of 200, 546 and 900 GeV. Pseudorapidity correlations interpreted in terms of a cluster model, which has been motivated by this and other experiments, require on average about two charged particles per cluster. The decay width of the clusters in pseudorapidity is approximately independent of multiplicity and of c.m. energy. The investigations of correlations in terms of pseudorapidity gaps confirm the picture of cluster production. The strength of forward-backward multiplicity correlations increases linearly with ins and depends strongly on position and size of the pseudorapidity gap separating the forward and backward interval. All our correlation studies can be understood in terms of a cluster model in which clusters contain on average about two charged particles, i.e. are of similar magnitude to earlier estimates from the ISR.

Multiplicity distributions of charged particles produced in non-single-diffractive collisions between protons and antiprotons at centre-of-mass energies of 200 and 900 GeV. The data were recorded in the UA5 streamer chambers at the CERN collider, which was operated in a pulsed mode between the two energies. This analysis confirms the violation of KNO scaling in full phase space found by the UA5 group at an energy of 546 GeV, with similar measurements at 200 and 900 GeV.
