Description

This analysis provides research of semileptonic decays of $B_s$ mesons on Belle experiment. The analysis makes use of hadronic tagging and is performed on 121.4 $\text{fb}^{−1}$ of data collected at $\Upsilon(5S)$ resonance state at the KEKB asymmetric energy $e^+ e^−$ collider located at the High
Energy Accelerator Research Organisation, Japan. The goal is to optimize the recovery of the lost neutrino's kinematics, taking into account possible pair production processes $B^*_{s}\bar{B^*_{s}}, B^*_{s}\bar{B_{s}} \,\text{and} \, B_{s}\bar{B_{s}}$. The study includes modeling of signal and background, estimation of backgrounds, optimization of selection.
