Detailed Description

This class projects out the incoming and outgoing leptons in a DIS event. The incoming lepton is assumed to be along the positive z-axis.

Constructor & Destructor Documentation

DISLepton (  Beam &  beam,
FinalState &  fsp,
const ParticleName &  inid,
const ParticleName &  outid
)  [inline]
 

The default constructor. Must specify the incoming and outgoing PDG codes of the leptons to project. If inid is an anti-particle and outid a particle, or vice versa, either a scattered lepton or anti-lepton is searched for. Must also specify a Beam and FinalState projection object which is assumed to live thoughout the run.

Member Function Documentation

Projection& addBeamPair (  const ParticleName &  beam1,
const ParticleName &  beam2
)  [inline, protected, inherited]
 

Add a colliding beam pair.

Definition at line 145 of file Projection.hh.

References Rivet::BeamPair.

Projection& addCut (  const string &  quantity,
const Comparison &  comparison,
const double  value
)  [inline, protected, inherited]
 

Add a cut.

Definition at line 151 of file Projection.hh.

Projection& addProjection (  Projection &  proj  )  [inline, protected, inherited]
 

Add a projection dependency to the projection list.

Definition at line 139 of file Projection.hh.

bool before (  const Projection &  p  )  const [inline, inherited]
 

Determine whether this object should be ordered before the object p given as argument. If p is of a different class than this, the before() function of the corresponding type_info objects is used. Otherwise, if the objects are of the same class, the virtual compare(const Projection &) will be returned.

int compare (  const Projection &  p  )  const [protected, virtual]
 

Compare with other projections.

Implements Projection.

virtual const set<BeamPair> getBeamPairs (   )  const [inline, virtual, inherited]
 

Return the BeamConstraints for this projection. Derived classes should ensure that all contained projections are registered in the _projections set for the beam constraint chaining to work.

virtual const Cuts getCuts (   )  const [inline, virtual, inherited]
 

Return the Cuts objects for this projection. Derived classes should ensure that all contained projections are registered in the _projections set for the cut chaining to work.
