Search for effects beyond Standard Model in photon scatterings and in nonminimal gauge theories on linear colliders of new generation
Abstract
The main possibilities of investigation of leptons and bosons production in interaction of polarized photons are considered. The usage of γγ ff[+γ] reactions for the luminosity measurement on linear photon collider is analyzed. The achievable precision of the luminosity measuring is considered and calculated. The first-order QED correction to γγ ll scattering is analyzed. All possible polarization states of interacting particles are investigated. For the detection of deviations from SM predictions at linear γγ colliders with center of mass energies running to 1 TeV the influence of three possible anomalous couplings on the cross sections of W+W- productions has been investigated. The significant discrimination between various anomalous contributions is discovered. The main contribution of high order electroweak effects is considered.
