Projected heavy ion physics performance at the High Luminosity LHC era with the CMS detector
CMS Collaboration
November 2017

Abstract: In this note, the projected performance of heavy ion physics in the HL-LHC era with the CMS detector is presented. The results are based on data from the pp, pPb and PbPb data taken between 2010 and 2016. The extrapolated performance with PbPb data corresponding to a total integrated luminosity of 10 nb$^{-1}$ at $\sqrt{s_{\rm NN}}= $ 5.02 TeV shows a dramatic improvement in the accuracy of a number of selected measurements using jets, quarkonia, and identified heavy flavor hadrons.
