It has been shown that the contribution of resonances in A7 asymmetry for the Standard Model increases from zero to 10*-4. The A7 asymmetry is very sensitive to new physics models, and can reach the value of 0.3. The calculations are useful in the analysis of experimental data and in the planning of experimental search for the effects of new physics at the Large Hadron Collider (LHC) and in the planning of experiments using lepton and photon beams with high luminosity, in particular, for precision measurements of the properties of light mesons, as well as for the search of new particles, e.g., in the project of research infrastructure IRIDE. We created Monte Carlo generator of random events that simulates meson production in an electron-photon process and their decay via two-photon channel. We simulated the angular distributions of the final particles. The dependence of the differential cross sections of the Borsellino-Cabibbo and Parisi contributions in the process of e-gamma ----> e-e+e- on the angle in the laboratory frame and the invariant mass of the lepton pairs was obtained. The values obtained for the cross sections indicate optimistically the possibility of the search of the vector gauge boson symmetry group U (1) "hidden sector" in the range of small masses. We considered the prospects of application of the lepton-lepton collider with high luminosity and a variable beam energy (~1-3 GeV) for precise measurement of hadron properties in the Standard Model and search for new ultralight particles beyond the Standard Model.
