A search is performed for Higgs-boson-mediated flavor changing neutral currents in the decay of a top quark to an up-type (c, u) quark and a Higgs boson, where the Higgs boson decays into dibosons or difermions. The proton-proton collision data set used corresponds to an integrated luminosity of 19.7 fb−1 at at center-of-mass of 8 TeV collected with the CMS detector at the LHC. Top quark pair events are searched for, in which one top quark decays to a charm or up quark and a Higgs and the other decays to a bottom quark and a W boson.
