In this paper we consider the process of "subthreshold" electron-positron pairs creation in the region of laser conversion. The total number of positrons and their distribution are obtained. This phenomena is offered for use as a good test to examine nonlinear effects of quantum electrodynamics on TESLA.
In this report our main attention is focused on the problems which can be solved at Photon Colliders naturally but are hardly solved at LHC and e^+e^- Linear Collider: The New Physics - new particles, new interactions, supersymmetry, Dirac monopole, extra dimensions... SM and the case of a SM--like scenario - EWSB, Higgs bosons, anomalies in interactions of gauge bosons, QCD, Pomeron and odderon... By-product: Production of light Goldstone particles from region of e\toγconversion.
By realizing the project of intensive $γ$ beams with large energy (necessary for Photon Colliders) an essential flux of light Goldstone particles (LGP - axions, arions, familons, majorons) can be generated. The probability of LGP production is calculated for different densities of laser photons in the conversion region (with absorption of one or several laser photons). The method for observation of LGP via its absorption in the matter is also presented.
It is shown that by realizing the project of intensive $γ$ beams with large energy (project PLC) an essential flux of light Goldstone particles (axions, arions, familons, majorons) will be generated. The light higgs can be observed via interaction with matter. The probability of light higgs - electron production by absorption of several laser photons simultaneously is calculated.
The polarization properties of the Compton effect in the field of a circularly polarized electromagnetic wave are discussed. In the case of nonlinear Compton effect the behavior of spin is analyzed. The transformation of the longitudinal polarization in the transverse polarization is showed. We obtained the total formulas describing the polarization of the final electron in the nonlinear case.
