Description
This analysis presents the top-quark background estimation for the $H\rightarrow Sh$ channel using the full Run-2 data, corresponding to an integrated luminosity of 139 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=$13 TeV.$~$The final state for this analysis is formed by two oppositely-charged leptons ($e^{\pm}\mu^{\mp},\mu^{\pm}e^{\mp},e^{\pm}\mu^{\mp}+ \mu^{\pm}e^{\mp}$) and jets. In this analysis the dominant Standard Model background are the top-quark processes ($t\bar{t}$ and $Wt$). The top control/validation regions are defined in the 1 b-jet and 2 b-jets phase space, respectively. The construction of the top-quark validation region is defined to correct the Monte Carlo mismodeling observed in the leptonic kinematics. Finally, the derived normalization factor in the top-quark control region is applied in the top-quark processes in both the control region and the signal region.
