Abstract

In this paper, we study the upper bounds on the mass insertion parameters (δ q AB ) ij in the minimal supersymmetric standard model. We found that the information from the measured branching ratio of B → X s l + l − decay can help us to improve the upper bounds on the mass insertions parameters (δ u , d AB ) 3 j , i 3 . Some regions allowed by the data of Br( B → X s γ) are excluded by the requirement of an SM-like C 7γ ( m b ) imposed by the data of Br( B → X s l + l − ).
