Muon pair production in the process $e^+ +e^- \to e^+ +e^- +\mu^+ + \mu^-$ by the two-photon collisions $\gamma \gamma \to \mu^+ \mu^-$ at high energies. The transverse momentum distributions

Abstract

In this present paper, we investigate the muon pairs production in the interaction between two quasireal photons in $e^+e^-$ collision. The total and differential cross section of the process $\gamma \gamma \to \mu^+\mu^-$ at a beam energy of photons from 3 GeV to 40 GeV in the center-of-mass and for different values of muon transverse momentum and the muon rapidity and the muon angle are calculated. We also study the total cross section, as a function of the $e^+ e^-$ center-of-mass energy $\sqrt {s}$ in the region 5 GeV $\leq \sqrt {s} \leq$ 209 GeV process of the $e^+ +e^- \to e^+ + e^- +\mu^+ + \mu^-$ by the two-photon mechanism. The obtained our results are in satisfactory agreement with the experimental data.
