We describe recent measurements of B and charm semileptonic and leptonic decay branching fractions and the determination of CKM matrix elements.

We propose an extension of the hypothesis of Minimal Flavour Violation (MFV) to general multi-Higgs Models without the assumption of Natural Flavour Conservation in the Higgs sector. We study in detail under what conditions the neutral Higgs couplings are only functions of $V_{CKM}$ and propose a MFV expansion for the neutral Higgs couplings to fermions.

The CDF experiment reports the first measurement of branching fractions
and CP-violating asymmetries
of doubly-Cabibbo suppressed B^+ --> D0 K decays in hadron collisions,
using the approach proposed
by Atwood, Dunietz, and Soni (ADS) to determine the CKM angle gamma. Using
5.0 fb-1 of data the combined significance of both
B^+ \to D0 pi/K signals exceeds 5sigma, and the ADS parameters...

Hadronic B decays offer rich opportunities for CP-violation studies. Decays of the type B -> DX, where D represents a charmed meson (D0, D(*)+ or D_s), allow for a theoretically clean determination of the CKM triangle angle γ which will provide a Standard Model benchmark of this quantity, robust against new physics effects. Decays into charmless final states, on the other hand, in general...
