Production of four charged leptons in elecroweak gamma gamma   interactions
  At present paper we performed a detailed numerical analysis of four charged leptons photoproduction in frame of standard theory of electroweak interaction. Total and differential cross sections are obtained by using of the Monte-Carlo method of numerical integration. Different energies of initial photons (60-2000 GeV in c.m.s.), definite and averaged spin states of interacting particles and fixed kinematical cuts are considered.
