We study model-independently the implications of nonstandard scalar and pseudoscalar
interactions for the decays b→ s γ, b→ sg, b→ s l+ l−(l= e, μ) and B s→ μ+ μ−. We find …

We perform an analysis of the K* polarization states in the exclusive B meson decay B 0→
K* 0 (→ K-π+) l+ l-(l= e, μ, τ) in the low dilepton mass region, where the final vector meson …

The present report documents the results of Working Group 2: B, D and K decays, of the
workshop on Flavor in the Era of the LHC, held at CERN from November 2005 through …

We discuss the three independent asymmetries, AT (2)(q2), AT (im)(q2) and AT (re)(q2), that
one can build from the amplitudes A_perp (q2) and A_par (q2). These quantities are …

We study the exclusive rare decay B → k ̄ l l. We calculate the relevant form factors within a
relativistic constituent quark model, for the first time without employing the impulse …

The large amount of data collected so far at B factories has allowed to reach a statistical
accuracy on B decays into pairs of (pseudo) scalars at a level where electromagnetic effects …

We consider measurements of exclusive rare semi-tauonic b-hadron decays, mediated by
the\(b\rightarrow s\tau^+\tau^-\) transition, at a future high-energy circular electron–positron …

The weak decays of Λ b→ Λ+ γ and Λ b→ Λ+ l+ l− are investigated in the standard model
using the light-cone sum-rule approach. The higher-twist distribution amplitudes of the Λ …

Hadronic form factors for the rare weak transitions Λb→ Λ (*) are calculated using a
nonrelativistic quark model. The form factors are extracted in two ways. An analytic …

The invariant mass spectrum, forward-backward asymmetry, and lepton polarizations of the
exclusive processes B→ K (K*) l+ l−, l= μ, τ are analyzed in a supersymmetric context …
