New Physics contributions to Delta F=2 transitions in models with constrained Minimal Flavour Violation (CMFV), are parametrized by a single variable S(v), the value of the real box diagram function.
- With already precise experimental values of epsilon_K, Delta M_d, Delta M_s, CP-asymmetry S_{psi K_S} and of hat{B}_K entering the evaluation of epsilon_K, the future of CMFV in the Delta F=2 sector depends crucially on the values of |Vcb|, |Vub|, gamma, F_{B_s} sqrt{hat B_{B_s}} and F_{B_d} sqrt{hat B_{B_d}}.
- The ratio xi of the latter two parameters, rather precisely determined from lattice calculations, allows then together with Delta M_s/Delta M_d and S_{psi K_S} to determine the range of gamma in the unitarity triangle independently of the value of S(v).
- Imposing in addition the constraints from epsilon_K and Delta M_d allows to determine the favorite CMFV values of |Vcb|, |Vub|, F_{B_s} sqrt{hat B_{B_s}} and F_{B_d} sqrt{hat B_{B_d}} as functions of S(v) and gamma.
