A study of the process e+ + e-→ e+ + e- + p + p¯ by the two-photon mechanism γγ → pp¯ 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 γγ → pp¯ 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 𝜃∗| is calculated. At energy <se+ e-> = 197GeV the total cross-section process of the e+ + e-→ e+ + e- + p + p¯ is calculated by the two-photon mechanism. The results are in satisfactory agreement with the experimental data.
