Abstract
A search for the production of heavy partners of the top quark with charge 5/3 is per- formed in events with a pair of same-sign leptons. The data sample corresponds to an integrated luminosity of 19.5 fb−1 and was collected at √s = 8 TeV by the CMS exper- iment. No significant excess is observed in the data above the expected background and the existence of top-quark partners with masses below 800 GeV is excluded at a 95% confidence level, assuming they decay exclusively to tW. This is the first limit on these particles from the LHC, and it is significantly more restrictive than previous limits.
