CSIC ORCID; CMS Collaboration | Fecha de publicación: | 2016 | Editor: | American Physical Society | Citación: | Physical Review D 93(7): 072004 (2016) | Resumen: | 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 corresponding to a luminosity of 19.7 fb-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 tt production. | Descripción: | et al. | Versión del editor: | https://doi.org/10.1103/PhysRevD.93.072004 | URI: | http://hdl.handle.net/10261/140545 | DOI: | 10.1103/PhysRevD.93.072004 | Identificadores: | doi: 10.1103/PhysRevD.93.072004 e-issn: 1550-2368 issn: 1550-7998 |
