We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

In the past decade, one of the major challenges of particle physics has been to gain an in-
depth understanding of the role of quark flavor. In this time frame, measurements and the …

B physics has played a prominent role in investigations of new physics effects at low-
energies. Presently, the largest discrepancy between a standard model prediction and …

We present the first unquenched lattice-QCD calculation of the hadronic form factors for the
exclusive decay B¯→ D ℓ ν¯ at nonzero recoil. We carry out numerical simulations on 14 …

This article reports world averages for measurements of b-hadron, c-hadron, and tau-lepton
properties obtained by the Heavy Flavor Averaging Group (HFAG) using results available at …

In the standard model, scalar contributions to leptonic and semileptonic decays are helicity
suppressed. The hypothesis of additional physical neutral/charged Higgses can enhance …

A bstract We address the impact of a modified W ℓν coupling on a wide range of
observables, such as τ leptonic and mesonic decays, leptonic decays of pseudoscalar …

We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element| V cb| and
the form-factor slope ρ 2 in B¯→ D ℓ-ν¯ ℓ decays based on 460× 10 6 BB¯ events recorded …

Recent experimental results for the ratio of the branching fractions of B→ D (∗) τ ντ and B→
D (∗) μνμ decays came as a surprise and lead to a discussion of possibility to constraining …

The semileptonic decay channel B→ D τ ν is sensitive to the presence of a scalar current,
such as that mediated by a charged-Higgs boson. Recently, the BABAR experiment reported …
