Abstract: (arXiv)

The mass of the top quark is measured using a sample of

t\bar{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 inverse femtobarns. The mass is reconstructed for each event employing a kinematic fit of the jets to a

t\bar{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.
