|ΔB|=1weak effective Lagrangian in the supersymmetric model with minimal flavor violation

Abstract

To evaluate the weak decays of b hadrons, the $\ensuremath{\Delta}B=1$ weak effective Lagrangian is the foundation. Any new physics beyond the standard model (SM) would contribute to the effective Lagrangian through the loop integration at the weak scale and evolution from the weak scale down to the hadronic scale. In this work we present a systematic analysis on the effective Lagrangian which mediates hadronic $|\ensuremath{\Delta}B|=1$ processes in the framework of the supersymmetric model with minimal flavor violation as well as a numerical evaluation of the Wilson coefficients in the effective theory.
