Description

This proceeding presents the top-quark background estimation for the $H\rightarrow Sh$ search.$~$The final state for this search is characterized by two leptons (electron and muon) and at least two jets. The top-quark is the dominant background contribution for this analysis. The analysis strategy defines the Signal, Control and Validation Regions which are in the phase space of 0 $b$-jet,1 $b$-jet and 2 $b$-jets respectively. The top-quark Validation Region is built to correct the Monte Carlo mismodeling observed in the leptonic kinematics.$~$Finally, the normalization factor is obtained in the top-quark Control Region to be applied to the top-quark background in the 1 $b$-jet and 0 $b$-jet phase space
