Hard Diffraction From Quasi - Elastic Dipole Scattering
The contribution to diffraction dissociation of virtual photons due to quasi-elastic scattering of the q-¯ q component is calculated in the framework of the QCD dipole picture. Both longitudinal and transverse components of the cross-section are given. It is shown that, at fixed mass of the diffractively produced system, quantum mechanical interference plays an important rôle. Phenomenological ...
متن کاملFinal state interaction effects in η photoproduction on two - and three - body nuclei
The role of final state interaction in η photoproduction on a deuteron as well as on three-body nuclei is investigated within few-body scattering theory. Deviation of the theory from the available experimental results is briefly discussed. 1. Incoherent η photoproduction on a deuteron Photoproduction of η mesons on the deuteron near threshold is strongly influenced by final state interaction (F...
متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...
متن کاملThe final - state interaction in the two - body nonleptonic decay of a heavy particle
We attempt to understand the final-state interaction in the two-body nonleptonic decay of a heavy particle for which many multibody (N ≥ 3) decay channels are also open. No matter how many multibody channels couple to the two-body channels, the analyticity of the S-matrix relates the phase and the magnitude of the two-body decay amplitude through a dispersion relation. In general, however, the ...
