Next-to-Leading Order QCD corrections to $B\bar{B}$-mixing and ${ϵ}_K$ within the MSSM

Abstract

We present a calculation of the QCD correction factors ${\eta }_{2B}$ and ${\eta }_{2K}$ up to Next-to-Leading Order within the MSSM. We took into account the region of low $\tan \beta$ for the Higgs- and chargino sector while neglecting the effect of gluinos and neutralinos.
