The Anatomy of Quark Flavour Observables in 331 Models in the Flavour Precision Era

Abstract

The coming flavour precision era will allow to uncover various patterns of flavour violation in different New Physics (NP) scenarios that are presently washed out by hadronic and experimental uncertainties. We illustrate this by performing the anatomy of flavour violation in the 331 models, based on the gauge group SU(3)_C X SU(3)_L X U(1)_X that are among the simplest NP scenarios with new sources of flavour and CP violation. The latter originate dominantly through the flavour violating interactions of ordinary quarks and leptons with a new heavy Z' gauge boson. After discussing first these models in some generality, we present a detailed study of Delta F=2 observables and of rare K and B meson decays in the specific beta=1/\sqrt{3} model (to be called overline{331} model) assuming significantly smaller uncertainties in CKM and hadronic parameters than presently available. The most prominent roles in our analysis play epsilon_K, Delta M_q (q=d,s), the mixing induced CP asymmetries S_{psi K_S} and S_{psi phi}, rare decays B_{s,d}-> mu^+ mu^- and in particular the CP-asymmetry S_{mu^+ mu^-}^s in B_s ->mu^+ mu^-. We identify a number of correlations between various observables that differ from those known from CMFV models. While, the Delta F=2 observables allow still for four oases in the new parameter space, we demonstrate how the inclusion of Delta F=1 observables can in the future identify the optimal oasis for this model. For 1 TeV <= M_{Z'}<= 3 TeV the overline{331} model is in good agreement with the recent data for B^+->tau^+ nu_tau, it removes the epsilon_K-S_{psi K_S} tension present in the SM and the epsilon_K-Delta M_{s,d} tension present in CMFV models. Simultaneously, while differing from the SM, it is consistent with the present data on BR(B_{s,d}->mu^+ mu^-) and S_{psi phi}. We identify the triple correlation BR(B_s->mu^+ mu^-)-S_{psi phi}-S_{mu^+ mu^-}^s.
