Abstract

We study the effects of sequential fourth quark generation in rare B --> K(K*)l(+)l(-) decays induced by the b --> s transition and in B-s(0)-(B) over bar (0)(s) mixing. Using the experimental values on the branching ratios of the B --> X(s)gamma and B --> K(K*)l(+)l(-) decays, the allowed regions for \VtbVts*\ and \Vt'bVt's*\ are determined as a function of the t' quark mass.
