The jet energy profile: A BSM analysis tool

Abstract

A new heavy di-jet resonance could be discovered at the 14 TeV LHC. In this talk we present a strategy to reveal the nature of such a particle; in particular to discern whether it is a quark–antiquark [Formula: see text], quark–gluon [Formula: see text], or gluon–gluon [Formula: see text] resonance. The strategy is based on the study of the energy profiles of the two leading jets in the di-jet channel. Including statistical uncertainties in the signal and the QCD backgrounds, we show that one can distinguish between [Formula: see text], [Formula: see text], and [Formula: see text] resonances; an evaluation of systematic uncertainties in the measurement of the jet energy profile will require a detailed detector study once sufficient 14 TeV di-jet data is in hand.
