Final 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 کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...
متن کاملFinal-State Interaction in Electron Scattering by Polarized Nuclei
The cross section for the reaction 39~ K(e, ep)Ar is computed, and the dependence of the FSI on the initial polarization angles of the nucleus K is analyzed. The results are explained in a semi-classical picture of the reaction. This procedure allows us to find the best initial kinematical conditions for minimizing the FSI.
متن کاملSimple classification of final state interaction effects in 4 He ( e , e ′ p ) scattering
A b s t r a c t The radius of interaction between the struck proton and spectator nucleons is close to the radius of short-distance two-nucleon correlations in nuclear matter, which makes final state interaction (FSI) an important background to production of protons with large missing momentum. We present a simple classification of the dominant FSI effects in 4 He(e, e ′ p) scattering and ident...
متن کاملMomentum distributions and final-state effects in neutron scattering.
A method for analyzing neutron-scattering data at intermediate and high-momentum transfer in liquids and solids is proposed. The aim is to separate the observed dynamic structure factor, $(Q, co), into its impulse-approximation (IA) and final-state (FS) parts. When the separation is made, both the IA and FS effects can be determined from the data. The method is based on a cumulant expansion of ...
