dc.description.abstract	Searches for anomalous top quark-antiquark production are presented, based on pp collisions at s√=8 TeV. The data, corresponding to an integrated luminosity of 19.7 fb(−1), were collected with the CMS detector at the LHC. The observed tt-bar invariant mass spectrum is found to be compatible with the standard model prediction. Limits on the production cross section times branching fraction probe, for the first time, a region of parameter space for certain models of new physics not yet constrained by precision measurements.
