    Get PDF
    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 Proceedings of Quark Confinement and the Hadron Spectrum VII, Ponta Delgada (Portugal), Sep 2-7, 200

    Semileptonic decays and ∣Vxb∣|V_{xb}| determinations

    Full text link
    We briefly summarize up-to-date results on the determination of the parameters of the Cabibbo-Kobayashi-Maskawa matrix ∣Vcb∣|V_{cb}| and ∣Vub∣|V_{ub}|, which play an important role in the unitarity triangle and in testing the Standard Model, and recent results on semileptonic BB meson decays involving a τ\tau lepton.Comment: Plenary talk at 6th International Conference on New Frontiers in Physics (ICNFP 2017), 17-26 Aug 2017, Kolymbari, Crete, Greece. arXiv admin note: text overlap with arXiv:1612.0376

    Tensions in the flavour sector

    Full text link
    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 BB decays and in RK/D(∗)R_{K/D^{(\ast)}} ratios. We also address the issue of the long standing tension in the ∣Vcb∣|V_{cb}| and ∣Vub∣|V_{ub}| exclusive/inclusive determinations.Comment: 9 pages, no figures, contribution to the Proceedings of the 12th Conference on Quark Confinement and the Hadron Spectrum (Confinement XII), 28 August-4 September 2016, Thessaloniki (Greece

    We review the current status of |V(cb)|, |V(ub)| and |V(tb)|, the absolute values of the matrix elements in the CKM third column.Comment: 24 pages, 2 figure

    CP violation with Bs

    Full text link
    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
