Abstract
We present the results of the angular analysis for $B^0\to\, K^*\left(892\right)^0\ell^+\ell^-$ using the full Belle data sample
corresponding to an integrated luminosity of $711\,\textrm{fb}^{-1}$. The obtained results are in agreement with the latest LHCb analyses and show a $2.1\,\sigma$ deviation from the DHMV Standard Model prediction in the range $4.0\,\textrm{GeV}^2 < q^2 < 8.0\,\textrm{GeV}^2$.
Furthermore we introduce a hadronic tagging procedure for $B_s$ mesons in the Belle $\Upsilon\left(5S\right)$ data sample that will open the opportunity to study leptonic and semi-leptonic \bs final states in future analyses.
