Description

In this paper, we study the upper bounds on the mass insertion parameters $(δ^{q}_{AB})_{ij}$ in the minimal supersymmetric standard model (MSSM). We found that the information from the measured branching ratio of $B \to X_s l^+ l^-$ decay can help us to improve the upper bounds on the mass insertions parameters $\left (δ^{u,d}_{AB})_{3j,i3}$. Some regions allowed by the data of $Br(B \to X_s γ) $ are excluded by the requirement of a SM-like $C_{7γ}(m_b)$ imposed by the data of $Br(B \to X_s l^+ l^-)$.
