A dynamical approach to semi-inclusive B decays
A dynamical approach to semi-inclusive decays based on an effective running
coupling for the strong interactions is described.Comment: 4 pages, 4 figures (reference added); to be published in the

Semileptonic D decays and eta-eta^prime mixing
We discuss the impact of recent progress in semileptonic D decays on light
flavour spectroscopy and estimate mixing parameters in the eta-eta^prime
system.Comment: 5 pages, no figures. Formal major changes to match the published

Tensions in the flavour sector
Flavour physics is currently well described by the Standard Model except for
some measurements which could be signalling new physics. We briefly summarize
the status of tensions in rare exclusive semi-leptonic decays and in
ratios. We also address the issue of the long standing
tension in the and exclusive/inclusive determinations.Comment: 9 pages, no figures, contribution to the Proceedings of the 12th

Studies of b-hadron decays to charming final states at LHCb
We present studies from the LHCb experiment of decays of the type H_b to H_c
X, where H_b represents a beauty hadron (B+, B0 or Lambda_b) and H_c a charmed
hadron (D0, D(*)+, Ds or Lambda_c). Such decays are important for the
determination of the CKM angle gamma, a key goal of the LHCb physics programme.
We exploit the data accumulated in 2010, and in the early months of the 2011
run. We report on the observation of new decay modes, and first measurements on
the road to a precise determination of gamma.Comment: To appear in the proceedings of the DPF-2011 Conference, Providence,
RI, August 201
Semileptonic decays and determinations
We briefly summarize up-to-date results on the determination of the
parameters of the Cabibbo-Kobayashi-Maskawa matrix and ,
which play an important role in the unitarity triangle and in testing the
Standard Model, and recent results on semileptonic meson decays involving a
lepton.Comment: Plenary talk at 6th International Conference on New Frontiers in

CP violation with Bs
The observation of CP violation effects is becoming more and more significant
in a variety of channels, due to the impressive experimental effort of the last
years. We review recent progress in Bs semileptonic decays and in Bs decays
into CP eigenstates.Comment: 4 pages. To appear in Proceedings of Rencontres de Moriond, QCD and
High Energy Interactions, La Thuile, March 10-17, 201
