Rivet analyses referenceCMS_2018_I1663452Search for new physics in dijet angular distributions using proton-proton collisions at sqrt(s) = 13 TeV and constraints on dark matter and other modelsExperiment: CMS (CERN LHC) Inspire ID: 1663452 Status: VALIDATED Authors:
Beam energies: (6500.0, 6500.0) GeV Run details:
Dijet angular distributions are measured in proton-proton collisions at sqrt(s)=13 TeV using based on a data set corresponding to an integrated luminosity of 35.9/fb collected by the CMS detector at the CERN LHC. Dijet angular distributions are found to be in agreement with the perturbative QCD predictions that include electroweak corrections. Source code: CMS_2018_I1663452.cc 1// -*- C++ -*-
