We use existing measurements of D − → K * 0 ρ − and B → ψ + K * , coupled with flavor independence of QCD, and with vector meson dominance to show that long distance contributions to B → ρ + γ are potentially very serious. We note that long distance (LD) contributions can be appreciably different in B − → ρ − + γ and B 0 → ρ 0 (ω) + γ. All radiative decays of B, B S are shown to be governed ess...

We use experimental information on D– d K*”p– and B ~ + + K“, coupled with flavor independence of QCD, and with vector meson dominance to show that long distance contributions to B + p+ T, especially to B– ~ p– + ~, are potentially very serious. Estimates based on the annihilation graph are shown to lead to similar conclusions. different in B~ p+ T and We emph=ize that long-distance (LD) contri...
متن کاملRadiative Penguin Decays from BABAR
Electroweak penguin decays provide a promising hunting ground for Physics beyond the Standard Model (SM). The decay B → Xsγ, which proceeds through an electromagnetic penguin loop, already provides stringent constraints on the supersymmetric (SUSY) parameter space [ 1]. The present data samples of ∼ 1 × 108BB̄ events allow to explore radiative penguin decays with branching fractions of the order...

متن کاملCharm meson radiative decays
Combining heavy quark effective theory and the chiral Lagrangian approach we investigate D meson radiative decays. First, we reanalyse D∗ → Dγ decays using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. Then, we calculate branching ratios D → V γ. We make some comments on the Cabbibo suppressed decays D → ρ/ωγ and the branching ratios of D → P...
