Jet correlation measurement in heavy-ion collisions: from RHIC to LHC

Abstract

We attempt to deduce simple options of `jet quenching' phenomena in heavy-ion collisions at $\text{snn}=5.5\text{tev}$ at the LHC from the present knowledge of leading-hadron suppression at RHIC energies. In light of the nuclear modification factor for leading particles we introduce the nuclear modification factor for jets, ${\text{RAA}}^{jet}$, and for the longitudinal momenta of particles along the jet axis, ${\text{RAA}}^{p_{\mathrm{L}}}$.
