Description
We present the results of searching for flavor-changing neutral current (FCNC) in the interaction of top quark and Higgs boson are presented. Large Hadron Collider (LHC) has accumulated proton-proton collision data corresponding to an integrated luminosity of 140 fb-1 at a center-of-mass energy of 13 TeV with the CMS detector during Run2. Using these datasets, the search is performed with the events of the final state of one isolated lepton, at least three jets including more than two b jets. Multivariate analysis techniques are utilized in various stages of analysis to improve the sensitivity of signal events. As no significant deviation is observed from the predicted background, we set upper limits on cross section and branching fraction of FCNC interaction in tHq coupling.
