Relativistic Contribution of the Final-state Interaction to Deuteron Photodisintegration
The contribution of the final-state interaction to the differential cross-section of deuteron photodisintegration at laboratory photon energies below 50 MeV is analyzed in the framework of Bethe–Salpeter formalism with a phenomenological rankone separable interaction. The approximations made are the neglect of two-body exchange currents, negative-energy components of the bound-state vertex func...
متن کاملHard two-body photodisintegration of 3He.
We have measured cross sections for the γ(3)He → pd reaction at photon energies of 0.4-1.4 GeV and a center-of-mass angle of 90°. We observe dimensional scaling above 0.7 GeV at this center-of-mass angle. This is the first observation of dimensional scaling in the photodisintegration of a nucleus heavier than the deuteron.
متن کاملAccurate Four-Body Response Function with Full Final State Interaction: Application to Electron Scattering off He
The longitudinal (e, e′) response function of 4He is calculated precisely with full final state interaction. The explicit calculation of the four-body continuum states is avoided by the method of integral transforms. Precision tests of the response show the high level of accuracy. Non–relativistic nuclear dynamics are used. The agreement with experimental data is very good over a large energy r...
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 ...
