This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …

We compute the form factors parametrizing radiative leptonic decays of heavy mesons B+→
γ e+ ν for photon energies much larger than Λ QCD, where perturbative QCD methods for …

We discuss factorization in exclusive radiative leptonic B→ γe ν ̄ decays using the soft-
collinear effective theory. The form factors describing these decays can be expanded in a …

We study the radiative decay B→ γℓνℓ in the framework of QCD factorization. We
demonstrate explicitly that, in the heavy-quark limit and at one-loop order in perturbation …

We study the weak radiative decays of B b→ B n γ with B b (n) the antitriplet bottomed (octet)
baryons in the light-front quark model. We obtain that B (Λ b→ Λ γ)=(7.1±0.3)× 10-6, which …

We calculate the weak transition form factors of the Λ b→ Λ (1520) transition, and further
calculate the angular distributions of the rare decays Λ b→ Λ (1520)(→ NK¯) ℓ+ ℓ-(NK¯={p K …

We review the physics of purely leptonic decays of $\pi^\pm $, $ K^\pm $, $ D^{\pm} $, $
D_s^\pm $, and $ B^\pm $ pseudoscalar mesons. The measured decay rates are related to …

We study the decays of B s, d→ l+ l− γ (l= e, μ, τ) within the light-front model. We calculate
the tensor type form factors and use these form factors to evaluate the decay branching …

We present two-loop calculations on the axial-vector form factors FA of semileptonic
radiative kaon and pion decays in chiral perturbation theory. The relevant dimension-6 terms …

We study the rare decays of Bs→ Msℓℓ (Ms= η, η′, φ and ℓ= ν, e, µ, τ) in the standard
model. With the hadronic form factors evaluated in the light front and constituent quark …
