Abstract
The presence of the anomalous top-quark flavor-changing neutral-current (FCNC) interactions leads to the production of same-sign top quarks in proton-proton collisions. The results of a search for events with same-sign dileptons and jets conducted by the CMS Collaboration with of data collected in collisions at are used to obtain the constraints on the strength of top-quark FCNC interactions. The 95% confidence level upper limits on the branching ratios of top-quark decays to a light quark and a gauge or a Higgs boson are set to be , , , and . The sensitivity of future searches in the same-sign top-quark channel is also presented.
