setProjectionHandler()

void Rivet::ProjectionApplier::setProjectionHandler ( ProjectionHandler &  projectionHandler ) const

protectedinherited

Todo:

AB: Add Doxygen comment, follow surrounding coding style

useInvisibles()

void Rivet::JetFinder::useInvisibles ( JetInvisibles  useinvis = JetInvisibles::DECAY )

inlineinherited

Include (some) invisible particles in jet construction.

The default behaviour is that jets are only constructed from visible particles. Some jet studies, including those from ATLAS, use a definition in which neutrinos from hadron decays are included via MC-based calibrations. Setting this flag to true avoids the automatic restriction to a VisibleFinalState.

useJetArea()

void Rivet::FastJets::useJetArea ( fastjet::AreaDefinition *  adef )

inline

Use provided jet area definition.

Warning

The provided pointer must be heap-allocated: it will be stored/deleted via a shared_ptr.

Note

Provide an adef null pointer to re-disable jet area calculation

useMuons()

void Rivet::JetFinder::useMuons ( JetMuons  usemuons = JetMuons::ALL )

inlineinherited

Include (some) muons in jet construction.

The default behaviour is that jets are only constructed from visible particles. Some jet studies, including those from ATLAS, use a definition in which neutrinos from hadron decays are included via MC-based calibrations. Setting this flag to true avoids the automatic restriction to a VisibleFinalState.
