Measurement of the top-quark mass in all-jets tt¯ events in pp collisions at vs=7 TeV

Abstract: The 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.
