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 tt¯ production.engrestrictedAccessarticle93700037357890000110.1103/PhysRevD.93.072004Standard modelLhcTevatronPhysicsDecayBoson2-s2.0-84966269131
