Search for flavor changing neutral current in top quark and Higgs boson interaction at $\sqrt{s}$ = 13 TeV

Searches for flavor changing neutral currents in production and decay of top quark pair and single top process using the data collected by the Compact Muon Solenoid (CMS) experiment at $\sqrt{s}$ = 13 TeV in 2016 is presented, corresponding to an integrated luminosity of 35.9 fb$^{-1}$.

Sumario:Searches for flavor changing neutral currents in production and decay of top quark pair and single top process using the data collected by the Compact Muon Solenoid (CMS) experiment at $\sqrt{s}$ = 13 TeV in 2016 is presented, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. Final states with one isolated lepton and at least three jets including 2 b-tagged jets are selected. In both single top (pp$\rightarrow$tH) and $\mathrm{t\bar t}$ (t$\rightarrow$qH) decays, only the H$\rightarrow \mathrm{b \bar b}$ decay is selected. No significant deviation is observed from the standard model prediction. Observed (expected) upper limits are obtained at 95% confidence level, which are B(t$\rightarrow$uH) < 0.47% (0.34%) and B(t$\rightarrow$cH) < 0.47% (0.44%).
