Quark-flavour violation in $h^0 \to b \bar{b}$ in the MSSM at one-loop level

We compute the width of the decay $h^0$ (125 GeV) $\to b \bar{b}$ at next-to-leading order in the general MSSM with quark-flavour violation (QFV). We study the effect of mixing between the second and the third generation of squarks, taking into account the constraints on QFV from B-mesondata. We discuss the renormalisation of the process as well as the resummationof the bottom Yukawa coupling at large $\tan \beta$. We show numerical results on the decay width $\Gamma(h^0 \to b \bar{b})$ as a function of the involved QFV parameters and compare them with the corresponding width in the Standard Model.
