Title: Measurement of the top-quark mass in all-jets $$t\bar{t}$$ events in pp collisions at $$\sqrt{s}$$=7 TeV

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.
