CP asymmetry for inclusive decay B→Xd+γ in the minimal supersymmetric standard model

We study the inclusive rare decay B→Xd+γ in the supergravity inspired Minimal Supersymmetric Standard Model and compute the CP-asymmetry in the decay rates. We show that there exist two phenomenologically acceptable sets of SUSY parameters: for one set the CP-asymmetry has the same (positive) sign as in the Standard Model and lies in the range (5–45)% while for the other set it is negative with values within −(2–21)%.
