Description
A measurement of the top-pair mass distribution in tt events is presented using proton-proton collision events at the LHC at a centre-of-mass energy of 7 TeV. The data are collected with the CMS experiment during the year 2011. The analysis is performed using several final states originating from top-pair production. The measurement is then used to search for massive resonances decaying into top-pairs. No significant deviations from the QCD expectations are observed, and upper limits on the new physics production cross-section as a function of the particle mass is determined
