Quark versus Gluon Jet Tagging Using Charged Particle Multiplicity with the ATLAS Detector

Distinguishing quark-initiated from gluon-initiated jets is useful for many measurements and searches at the LHC. This note presents a quark-initiated versus gluon-initiated jet tagger using the number of charged particle tracks inside the jet. For a 60\% quark jet efficiency working point, a gluon...

description Distinguishing quark-initiated from gluon-initiated jets is useful for many measurements and searches at the LHC. This note presents a quark-initiated versus gluon-initiated jet tagger using the number of charged particle tracks inside the jet. For a 60\% quark jet efficiency working point, a gluon jet efficiency between 10 and 20\% is achieved across a wide range in jet $p_\text{T}$ with systematic uncertainties that are about 5\%.
