Forward coherent ω and ϕ mesons production in the photonuclear reaction on nuclei

Abstract

The differential cross sections of the forward coherent ω and φ mesons photoproduction from nuclei have been calculated using the Glauber model for the nuclear reaction. The measured cross section of the elementary reaction, i.e., γN → ω(φ)N reaction, are used as input in the Glauber model. The experimentally determined free-space scattering parameters of the quoted mesons have been used to evaluate the meson nucleus interactions. The sensitivity of the cross section to the Fermimotion of the nucleon and the nucleon-nucleon short-range correlation in the nucleus are studied. The calculated results are compared with the measured cross sections.
