| 摘要: | 摘要： 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=8TeV corresponding to a luminosity of 19.7fb super(-1). The top quark mass is measured using the lepton+jets, all-jets and dilepton decay channels, giving values of 172.35+ or -0.16(stat)+ or -0.48(syst)GeV, 172.32+ or -0.25(stat)+ or -0.59(syst)GeV, and 172.82+ or -0.19(stat)+ or -1.22(syst)GeV, respectively. When combined with the published CMS results at s=7TeV, they provide a top quark mass measurement of 172.44+ or -0.13(stat)+ or -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 tt production.
