Abstract
A new set of measurements of the top quark mass are presented, based on the proton-proton data recorded by the CMS experiment at the LHC at
√s = 8 TeV responding to a luminosity of 19.7 fb[superscript −1]. The top quark mass is measured using the lepton+ jets, all-jets and dilepton decay channels, giving values of 172.35 ± 0.16(stat)±0.48(syst) GeV, 172.32±0.25(
stat)±0.59(syst) GeV, and 172.82±0.19(stat)±1.22(syst) GeV, respectively. When combined with the published CMS results at √s = 7 TeV, they provide a top quark mass measurement of 172.44±0.13(stat)±0.47(syst) GeV. The top quark mass is also studied as a function of the event kinematical properties in the lepton + jets decay channel. No indications of a kinematic bias are observed and the collision data are consistent with a range of predictions from current theoretical models of t[bar over t] production.
