Query: Lepton polarization correlations in $B \to K^* \tau^- \tau^+$   In this work we will study the polarizations of both leptons ($\tau$) in the
decay channel $B\to K^* \tau^- \tau^+$. In the case of the dileptonic inclusive
decay $B\to K^* \ell^- \ell^+$, where apart from the polarization asymmetries
of single lepton $\ell$, one can also observe the polarization asymmetries of
both leptons simultaneously. If this sort of measurement is possible then we
can have, apart from decay rate, FB asymmetry and the six single lepton
polarization asymmetries (three each for $\ell^-$ and $\ell^+$), nine more
double polarization asymmetries. This will give us a very useful tool in more
strict testing of SM and the physics beyond. We discuss the double polarization
asymmetries of $\tau$ leptons in the decay mode $B\to K^* \tau^- \tau^+$ within
the SM and the Minimal Supersymmetric extensions of it.
