Motivated by the recently improved results from the Fermilab Lattice and MILC Collaborations on the hadronic matrix elements entering (Formula presented.) in (Formula presented.) – (Formula presented.) mixing, we determine the universal unitarity triangle (UUT) in models with constrained minimal flavour violation (CMFV). Of particular importance are the very precise determinations of the ratio (Formula presented.) and of the angle (Formula presented.). They follow in this framework from the experimental values of (Formula presented.) and of the CP-asymmetry (Formula presented.). As in CMFV models the new contributions to meson mixings can be described by a single flavour-universal variable S(v), we next determine the CKM matrix elements (Formula presented.) , (Formula presented.) , (Formula presented.) and (Formula presented.) as functions of S(v) using the experimental value of (Formula presented.) as input. The lower bound on S(v) in these models, derived by us in 2006, implies then upper bounds on these four CKM elements and on the CP-violating parameter (Formula presented.) , which turns out to be significantly below its experim ... mehr
