Search for the flavor-changing neutral current interactions of the top quark and the Higgs boson which decays into a pair of b quarks at √ s = 13 TeV

A search for flavor-changing neutral currents (FCNC) in events with the top quark and the Higgs boson is presented. The Higgs boson decay to a pair of b quarks is considered. The data sample corresponds to an integrated luminosity of 35.9 fb−1 recorded by the CMS experiment at the LHC in proton-prot...
