Résumé : We investigate the possible size of h→bs in two-Higgs-doublet models with generic Yukawa couplings. Even though the corresponding rates are in general expected to be small due to the indirect constraints from Bs→μ+μ- and Bs-B̄s mixing, we find regions in parameter space where h→bs can have a sizable branching ratio well above 10%. This requires a tuning of the neutral scalar masses and their couplings to muons, but then all additional constraints such as B→Xsγ, (g-2)μ, and h→μ+μ- are satisfied. In this case, h→bs can be a relevant background in h→bb̄ searches and vice versa due to the imperfect b-tagging purity. Furthermore, if h→bs is sizeable, one expects two more scalar resonances in the proximity of mh. We briefly comment on other flavor-violating Higgs decays and on the 95 GeV γγ resonance within generic two-Higgs-doublet models.
