Abstract: Searches for anomalous top quark-antiquark production are presented, based on pp collisions at $\sqrt{s}$ = 8 TeV. The data, corresponding to an integrated luminosity of 19.7 inverse femtobarns, were collected with the CMS detector at the LHC. No excess of events above the yield expected from the standard model is observed. 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.
