Top quark mass measurement in the $\mathrm{t}\overline{\mathrm{t}}$ all-jets final state with the CMS experiment at $\sqrt{s}=13\mathrm{TeV}$

Abstract

The top quark mass is measured using $35.9{\mathrm{fb}}^{-1}$ of LHC proton-proton collision data collected with the CMS detector at $\sqrt{s}=13\mathrm{TeV}$ in 2016. The measurement uses the $\mathrm{t}\overline{\mathrm{t}}$ all-jets final state, which comprises a total of six jets. A kinematic fit is performed to reconstruct the decay of the $\mathrm{t}\overline{\mathrm{t}}$ system and suppress QCD multijet background. By means of the ideogram method, the top quark mass is determined, simultaneously constraining an additional jet energy scale factor ($\text{JSF}$). The result of $172.34\pm 0.20\text{(stat+JSF)}\pm 0.76\text{(syst)}\mathrm{GeV}$ for the top quark mass is in good agreement with previous measurements in the same and different final states.
