A study of the process $e^{+}+e^{-}\to e^{+}+e^{-}p\bar{p}$ by the two-photon mechanism $\gamma \gamma \to p\bar{p}$ at high energies

Abstract

In this paper we consider the exclusive production of proton-antiproton pairs in the interaction between two quasireal photons in $e^{+}{e}^{-}$ collision. The differential and total cross section of the process $\gamma \gamma \to p\bar{p}$ at a beam energy of photons from 2.1 GeV to 4.5 GeV in the center-of-mass and for different values of $|cos{\theta }^{\ast }|$ is calculated. At energy $<\sqrt{s_{e^{+}{e}^{-}}}>$=197 \,\,GeV the total cross section process o0f the $e^{+}+e^{-}\to e^{+}+e^{-}+p+\bar{p}$ is calculated by the two-photon mechanism. The results are in satisfactory agreement with the experimental data.
