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 …

The short-distance Hamiltonian describing b→ s (d) e− e+ in the standard model is used to
obtain the decay spectrum of B→ K− π+ e− e+ and B→ π− π+ e− e+, assuming the K π and …

We study the exclusive semileptonic B-meson decays B→ K (π) ℓ+ ℓ-, B→ K (π) ν ν¯, and
B→ π τ ν, computing observables in the Standard Model using the recent lattice-QCD results …

The rare decay B→ π ℓ+ ℓ-arises from b→ d flavor-changing neutral currents and could be
sensitive to physics beyond the standard model. Here, we present the first ab initio QCD …

∗ 0 µ+ µ−)=[2.9±1.0 (stat)±0.2 (syst)±0.3 (norm)]× 10− 8, where the first and second
uncertainties are statistical and systematic, respectively. The third uncertainty is due to …

We discuss the uses of conversion electron pairs for extracting photon polarization
information in weak radiative B decays. Both cases of leptons produced through a virtual …

A search for the rare decays B s 0→ π+ π− μ+ μ− and B 0→ π+ π− μ+ μ− is performed in a
data set corresponding to an integrated luminosity of 3.0 fb− 1 collected by the LHCb …

We study the rare decays B u+→ π+ ℓ+ ℓ-, ρ+ ℓ+ ℓ-and B d 0→ ℓ+ ℓ-(ℓ= e, μ) in the R-parity
violating supersymmetric standard model. From the latest upper limits of B (B u+→ π+ ℓ+ ℓ-) …

The LHCb experiment observed B+→ π+ μ+ μ-decay with 1.0 fb-1 data, which is the first
measurement of a flavor changing neutral current b→ d ℓ+ ℓ-decay (ℓ= e, μ). Based on QCD …

Exclusive semileptonic decays based on b→ s transitions have attracted a lot of attention as
some angular observables deviate significantly from the standard model (SM) predictions. B …
