Abstract
A search for resonances decaying to top quark-antiquark pairs is performed using a data sample recorded by the CMS experiment at the LHC in collisions at corresponding to an integrated luminosity of . No significant deviations from the standard model background are observed. Upper limits are presented for the production cross section times branching fraction of top quark-antiquark resonances for masses from 750 to 3000 GeV. In particular, the existence of a leptophobic topcolor particle is excluded at the 95% confidence level for resonance masses for , and for .
