Abstract

The mass of the top quark is measured using a sample of t¯t 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 √s = 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 t¯t 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 byCMSyields a mass of 173.54±0.33 (stat.)±0.96 (syst.) GeV.
