In the present paper, we investigate the muon pair production in the interaction between two quasi-real photons in e+e- collision. We calculate the total and differential cross section of the process γγ→ μ+μ- at a beam energy of photons from 3 to 40 GeV in the center-of-mass and for different values of the muon transverse momentum, the muon rapidity and the muon angle. In the γγ→ μ+μ- process we also take the contribution of the Box+Vertex correction+ Soft photon emission+Vacuum polarization diagrams. We also study the cross section of the e++ e-→ e++ e-+ μ++ μ- process as a function of the e+e- center-of-mass energy s in the region 5 GeV ≤s≤ 209 GeV using the two-photon mechanism. The obtained results are in satisfactory agreement with experimental data.
