In particular we focus on Bs->KK decays, for which we present complementary predictions within the SM, as well as the impact that SUSY would have on the CP observables. We also present an analysis of Bs->VV decays that allows to measure the mixing angle of the Bs system. We make special emphasis on the control of hadronic uncertainties.PhD Thesis, 150 pagesHigh Energy Physics - Phenomenologytext
