Abstract:

A study of the resolved reconstruction of top quark pairs in the e/

\mu

+jets channels and a projection of differential

\mathrm{t\bar{t}}

cross section measurements at the HL-LHC with an integrated luminosity of 3 ab

^{-1}

at 14 TeV are presented. The analysis techniques are based on previous measurements of differential

\mathrm{t\bar{t}}

cross sections at 13 TeV. It is shown that such a measurement is feasible at the HL-LHC despite the expected large number of pileup interactions. The precision of the differential cross section will profit from the enormous amount of data and the extended

\eta

-range of the Phase-2 CMS detector. The results are used to estimate the improvement of constraints on parton distribution functions.
