Gauge-invariant Approach to Meson Photoproduction including the Final-state Interaction
A gauge-invariant formalism is presented for the practical treatment of photoand electroproduction of pseudoscalar mesons off nucleons that allows an explicit incorporation of hadronic final-state interactions. The semi-phenomenological approach is based on a field theory developed by one of the authors. It generalizes an earlier approach by allowing for systematic improvement of approximations...
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 کاملFinal State Interactions in Near Threshold Meson
We analyse the experimental data on near threshold π, η, ω, η ′ and K + production from pp collisions and show that all information gained so far is compatible with approximately constant production matrix elements when including the rescattering between the baryons in the final states. Different methods to include the final state interactions are discussed and their range of validity is indica...
متن کاملScalar Meson Photoproduction
The light-quark non-strange scalar mesons a0(980), f0(980), f0(1370), a0(1450), f0(1500) and f0(1710) are of great interest as there is no generally accepted view of their structure which can encompass qqq̄q̄, molecular, qq̄ and glueball states in various combinations. It has been shown previously that the radiative decays of the scalar mesons to ρ and ω are a good probe of their structure and pro...
متن کاملTransversity and Meson Photoproduction
Both meson photoproduction and semi-inclusive deep inelastic scattering can potentially probe transversity in the nucleon. We explore how that potential can be realized dynamically. The role of rescattering in both exclusive and inclusive meson production as a source for transverse polarization asymmetry is examined. We use a dynamical model to calculate the asymmetry and relate that to the tra...
