Abstract (data abstract)
CERN-LHC. Searches for anomalous top quark-antiquark production are presented, corresponding to an integrated luminosity of 19.7 inverse femtobarns, recorded in 2012 with the CMS detector from pp collisions at sqrt(s) = 8 TeV. No excess of events above the yield expected from the standard model is observed. Limits are placed on the production cross section times branching fraction for certain models of new physics. UPDATE (03 FEB 2014): Zprime events in last column of Table 3 (Figure 1C) were incorrectly normalized by a factor of 10, corresponding to a signal cross section of 0.1 pb instead of 1.0 pb stated in the caption of Figure 1 of the paper; this mistake has now been corrected in Table 3.
