2 00 4 Stokes Vector of Photon in the Decays B 0 → ρ 0 γ and B 0 → K ∗ γ
نویسندگان
چکیده
We consider a model for the decay B 0 → ρ 0 γ in which the short-distance amplitude determined by the Hamiltonian describing b → dγ is combined with a typical long-distance contribution B 0 → D + D − → ρ 0 γ. The latter possesses a significant dynamical phase which induces a CP-violating asymmetry A CP , as well as an important modification of the Stokes vector of the photon.

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...
متن کاملDirect CP Violation in B Decays
We discuss several aspects of direct CP asymmetries in B decays, which are very useful in spite of hadronic uncertainties in asymmetry calculations. 1) Asymmetries in decays to D(∗)K(∗), π+π−, ρ+ρ−, providing precision tests for the CKM phase γ. 2) Null tests in B+ → J/ψK+, π+π0, where a nonzero asymmetry provides evidence for New Physics. 3) Isospin and broken flavor SU(3) relations among CP a...

We calculate the so-called hard spectator corrections in O(α s) in the leading-twist approximation to the decay widths for B → K * γ and B → ργ decays and their charge conjugates, using the Large Energy Effective Theory (LEET) techniques. Combined with the hard vertex and annihilation contributions, they are used to compute the branching ratios for these decays in the next-to-leading order (NLO...

The weak radiative Cabibbo allowed decays D + → ¯ K 0 π + γ and D 0 → K − π + γ with nonresonant Kπ are investigated by relying on the factorization approximation for the nonleptonic weak transitions and the model which combines the heavy quark effective theory and the chiral Lagrangian approach. The dominant contributions to the amplitudes come from the long distance effects. The decay amplitu...
