Helicity amplitude method for two electron positron pairs photoproduction
T. Shishkina, I. Sotsky
We present the matrix element of gamma gamma ->4l process with four charge particles in final state. The constructions are performed in frame of Standard Model of electroweak inter…
The finite mass calculations for Gamma Gamma --> L+ L- Gamma process
V. V. Makarenko, T. V. Shishkina
The process will be used for the photon beams luminosity measurement when the total angular momentum of colliding photons equals zero. The previous studies of thi…
Study of Quartic Boson Vertices at Photon Colliders in the Standard Model and Beyond
I. Marfin, V. Mossolov, T. Shishkina
The production of several vector bosons in -interactions is the best place to search directly for any anomalous behavior of triple and quartic couplings. A few anomalous quarti…
Anomalous quartic boson couplings via gamma gamma --> WW and gamma gamma --> WWZ at the TESLA kinematics
I. B. Marfin, V. A. Mossolov, T. V. Shishkina
The production of two and three electroweak gauge bosons in the high-energy collisions gives the well opportunity to probe anomalous quartic gauge boson couplings. The influen…
