Abstrakt

We compute the width of the decay h⁰(125 GeV) → bb 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-meson data. We discuss the renormalisation of the process as well as the resummation of the bottom Yukawa coupling at large tanβ. We show numerical results on the decay width Γ(h⁰ → bb) as a function of the involved QFV parameters and compare them with the corresponding width in the Standard Model.
