Recent Results on Radiative and Electroweak Penguin Decays of B Mesons at BaBar

الأصل · EN

Radiative and electroweak decays of B mesong (B to Xₛ₍d₎γ and B to Xₛ₍d₎ℓℓ, respectively, where X is a hadronic system and s or d labels the underlying quark process b to s(d)γ) provide good places to search for new physics (NP) beyond the standard model. Recent BaBar measurements are reported: inclusive BF(B to Xₛ γ), direct CP asymmetry for inclusive Xₛ γ and Xₛ₊d γ, and searches for the rare decays B to π(η)ℓℓ. No evidence for NP was found, but several constraints are discussed.
