000003226 520__ $$aIn the semileptonic decay of $B$ mesons, the global average of $R(D^{*})$ measurement deviates from the Standard Model by $3.3\sigma$. It indicates a violation of the lepton universality. We will measure $R(D^{*})$ for the validation of this deviation using the Belle II data, which are independent of the previous measurements’ data. We have developed an analysis method employing the hadronic tag algorithm. In this talk, we will report the method and discuss the expected sensitivity in this analysis with data collected by the summer of 2022.
