Quark-Hadron Duality, Factorization and Strong Phases in B0_d+- Decay

چکیده
We consider the hadronic description of the B0 d → π+π− decay, with the aim to investigate the strong phases generated by the final state interactions. The derivation of the dispersion relations using the Lehmann-Symanzik-Zimmermann formalism and the Goldberger-Treiman method to include inelastic effects in the spectral function are presented. We discuss the problem of quark-hadron duality and estimate in the hadronic formalism the corrections to the factorized amplitude in the heavy quark limit.

0 Quark - Hadron Duality , Factorization and Strong Phases in B 0 d → π + π − Decay
We investigate the hadronic description of the B 0 d → π + π − decay, with the aim to test the validity of quark-hadron duality, the factorization limit and the magnitude of the strong phases. We discuss the derivation of the dispersion relations in the Lehmann-Symanzik-Zimmermann formalism, the Goldberger-Treiman method to include inelastic effects in the spectral function and the consistency ...

متن کاملFactorization versus duality in nonleptonic decays: A quark model approach.
Abstract We study in a quark model the contradiction between factorization and duality found in nonleptonic decays at next to leading order in 1/Nc, concentrating on quark exchange mechanism. The contradiction originates in the fact that the standard factorization assumption approximates the asymptotic final states by a non-orthogonal set of states, thus leading to an overcounting of the decay ...
متن کاملQuark-Hadron Duality in Electron Scattering
Quark-hadron duality addresses some of the most fundamental issues in strong interaction physics, in particular the nature of the transition from the perturbative to non-perturbative regions of QCD. I summarize recent developments in quark-hadron duality in lepton–hadron scattering, and outline how duality can be studied at future high-luminosity facilities such as Jefferson Lab at 12 GeV or an...
متن کاملExplicit Quark - hadron Duality in Heavy - light Meson Weak Decays in the ’ t Hooft Model
We compute the nonleptonic weak decay width of a heavy-light meson in 1+1 spacetime dimensions with a large number of QCD colors (the ’t Hooft model) as a function of the heavy quark mass. In this limit, QCD is exactly soluble, and decay modes are dominated by two-particle final states. We compare the results to the tree-level partonic decay width of the heavy quark in order to test quark-hadro...
