dc.description.abstractThe mass of the top quark is measured using a sample of tt¯ candidate events with at least six jets in the final state. The sample is selected from data collected with the CMS detector in pp collisions at vs=7 TeV in 2011 and corresponds to an integrated luminosity of 3.54 fb-1. The mass is reconstructed for each event employing a kinematic fit of the jets to a tt¯ hypothesis. The top-quark mass is measured to be 173.49±0.69(stat.)±1.21(syst.) GeV. A combination with previously published measurements in other decay modes by CMS yields a mass of 173.54±0.33(stat.)±0.96(syst.) GeV.es_ES
dc.description.sponsorshipWe congratulate our colleagues in the CERNaccelerator departments for the excellent performance of the LHC andthank the technical and administrative staffs at CERN and at other CMSinstitutes for their contributions to the success of the CMS effort. Inaddition, we gratefully acknowledge the computing centres and per-sonnel of the Worldwide LHC Computing Grid for delivering so effec-tively the computing infrastructure essential to our analyses.
