【 摘 要 】

The Minimal Supersymmetric Standard Model assumes scalar masses universality as a simplification to avoid undesired flavor changing neutral currents (FCNC). In this work, we consider that the trilinear SUSY soft-terms have a hierarchical structure of flavor mixing within generations, leading to a non-degeneration on sfermion masses preserving FCNC under control. We consider this kind of mixing for the u-type squark mass matrix and analyze the consequences on the radiative corrections to the Higgs mass. We work under the consideration of mmaxhbenchmark scenario, in which the parameter space is set to maximize the radiative contributions to the Higgs mass. Based on recent experimental results on possible Higgs signals, we calculate the mass of the neutral light CP-even Higgs taking into account flavor mixing contributions.
