JET_BTAG_ATLAS_RUN1()

double Rivet::JET_BTAG_ATLAS_RUN1 ( const Jet & j )

inline

Return the ATLAS Run 1 jet flavour tagging efficiency for the given Jet, from Delphes.

Todo

This form drops past ~100 GeV, asymptotically to zero efficiency... really?!

JET_SMEAR_ATLAS_RUN1()

Jet Rivet::JET_SMEAR_ATLAS_RUN1 ( const Jet & j )

inline

ATLAS Run 1 jet smearing.

Implemented by Matthias Danninger for GAMBIT, based roughly on https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/CONFNOTES/ATLAS-CONF-2015-017/

Todo

Also need a JES uncertainty component?

Todo

Is this the best way to smear? Should we preserve the energy, or pT, or direction?
