Detailed Description

Wrapper projection for smearing Jets with detector resolutions and efficiencies.

Todo:

Allow applying a pre-smearing cut so smearing doesn't need to be applied to below-threshold micro-jets

setProjectionHandler()

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.

useMuons()

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

inlineinherited

Include (some) muons in jet construction.
