Fourth generation effects in processes induced by "b -> s" transition
Abstract
We study the effects of sequential fourth quark generation in rare "B -> K(K*) l+ l-" decays induced by "b -> s" transition and in "Bs0 - barBs0" mixing. Using the experimental values on branching ratios of the "B -> Xs gamma" and "B -> K(K*) l+ l-" decays, the allowed regions for Vtb Vts and "|Vt'b Vt's*| are determined as a function of the (t') quark mass.
