Constraining nuclear parton distributions with heavy ion collisions at the HL-LHC with the CMS experiment

Recent measurements in heavy ion collisions by the CERN LHC Collaborations have been used to assess nuclear effects and provide valuable data for nuclear parton distribution analyses. In this note, performance studies for measurements with the CMS detector at the High-Luminosity LHC (HL-LHC) are presented. These include the coherent $\Upsilon(1S)$ photoproduction in ultraperipheral lead-lead collisions, corresponding to a total integrated luminosity of 10 $\mathrm{nb}^{-1}$ at a nucleon-nucleon (NN) center-of-mass energy ($\sqrt{\smash [b]{s_{_{\mathrm {NN}}}}}$) of 5.5 TeV. This note also presents the performance studies at the HL-LHC for analyses of inclusive Z boson, dijet, and top quark pair production in proton-lead collisions at $\sqrt{\smash [b]{s_{_{\mathrm {NN}}}}}=8.16$ TeV for an integrated luminosity of 2 $\mathrm{pb}^{-1}$.
