PREDICTIONS FOR FLAVOUR OBSERVABLES IN A RS MODEL WITH CUSTODIAL SYMMETRY

In these proceedings we present the main results for particle antiparticle mixing and rare decays in the Randall Sundrum (RS) model with custodial symmetry. To investigate the strong bound on the Kaluza-Klein (KK) mass scale M(KK) greater than or similar to O(20) TeV implied by the measurement of epsilon(K) we perform a fine-tuning analysis that, on the one hand, confirms the quoted bound on the KK mass scale but, on the other hand, reveals that consistence with experiment can still be achieved for small or moderate fine-tuning. In our analysis of rare decays of K and B mesons we find that due to the custodial symmetry the coupling of the Z boson to right handed quarks yields the dominant contribution. This feature of the model leads to distinct patterns and correlations that allow to distinguish the model from other frameworks of physics beyond the Standard Model (SM).
