## Abstract

The mass of the top quark is measured using a sample of $\text{t}\bar{\mathrm{t}}$ 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 $\sqrt{s}$ = 7 TeV in 2011 and corresponds to an integrated luminosity of 3.54 $\text{f}b^{−1}$ . The mass is reconstructed for each event employing a kinematic fit of the jets to a $\text{t}\bar{\mathrm{t}}$ hypothesis. The top-quark mass is measured to be 173.49 $\pm$ 0.69(stat.) $\pm$ 1.21(syst.) GeV. A combination with previously published measurements in other decay modes by CMS yields a mass of 173.54 $\pm$ 0.33(stat.) $\pm$ 0.96(syst.) GeV.
