Abstract:
Motivated by the recent measurement of low longitudinal polarization fraction in the decay mode \B \to \phi K^{*0}, which appears not to be in agreement with the standard model expectation, we analyze this mode in the minimal supersymmetric standard model with mass insertion approximation. Within the standard model, with factorization approximation, the longitudinal polarization is expected to be fL1O(1/mb2)f_L \sim 1-{\cal O}(1/m_b^2). We find that this anomaly can be explained in the minimal supersymmetric standard model with either LRLR or RLRL mass insertion approximation.
