Zweig-rule-satisfying inelastic rescattering in B decays to pseudoscalar mesons
نویسنده
چکیده
We discuss all contributions from Zweig-rule-satisfying SU(3)-symmetric inelastic FSI-induced corrections in B decays to ππ, πK, KK̄, πη(η′), and Kη(η′) . It is shown how all of these FSI corrections lead to a simple redefinition of the amplitudes, permitting the use of a simple diagram-based description, in which, however, weak phases may enter in a modified way. The inclusion of FSI corrections admitted by the present data allows an arbitrary relative phase between the penguin and tree short-distance amplitudes. The FSI-induced error of the method, in which the value of the weak phase γ is to be determined by combining future results from B+, B0 d , B 0 s decays to Kπ, is estimated to be of the order of 5o for γ ≈ 50o − 60o.

New results going beyond those obtained from isospin and flavor symmetry and subject to clear experimental tests are obtained for effects of FSI in B decays to charmless strange final states containing neutral flavor-mixed mesons like ω, φ, η and η. The most general strong-interaction diagrams containing arbitrary numbers of quarks and gluons are included with the assumptions that any qq̄ pair c...
متن کاملSearching for dominant rescattering sources in B to two pseudoscalar decays
Various rescattering sources are analyzed in the context of the SU(3) flavor symmetry. In particular, the possibility to account for intermediate charm at the hadronic level in B to PP is thoroughly investigated. Then, the rescattering sources are compared in light of recent B to two charmless pseudoscalar decay measurements, with emphasis on the size of strong phases and on patterns of direct ...
متن کاملU-spin Symmetry in Charmless B Decays
We prove a general theorem about equal CP rate differences within pairs of U-spin related charmless B and Bs decays. Six pairs of decays into two pseudoscalar mesons are identified where such relations hold. Ratios of corresponding rate differences and certain ratios of rates measure U-spin breaking. These processes provide useful information on the weak phase γ = ArgV ∗ ub. Applications of U-s...

removes spurious selection rule forbidding processes with odd number of Goldstone mesons. Pseudoscalar mesons are produced in e+e− annihilation via vector resonances, hence one should include vector mesons in a chiral invariant way. The problem of testing chiral models of the vector meson interactions with Goldstone bosons is acute because in well studied decays ρ → 2π, ω → 3π the final pions a...

Recently Belle has established the 90% confidence level (CL) upper limit B < 9.4× 10 for the branching ratio for B → J/ψφ, a process expected to be suppressed by the Okubo-Zweig-Iizuka (OZI) rule disfavoring disconnected quark diagrams. We use information on ω–φ mixing to establish likely lower bounds on this and related processes. We find that the Belle result is about a factor of five above o...
