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

arXiv:1510.03714

Abstract

We compute the width of the decay $h^{0}$ (125 GeV) $\to b b ˉ$ 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 $tan β$ . We show numerical results on the decay width $Γ (h^{0} \to b b ˉ)$ as a function of the involved QFV parameters and compare them with the corresponding width in the Standard Model.
