Photon-Photon Scattering at the Photon Linear Collider

Abstract

Photon-photon scattering at the Photon Linear Collider is considered. Explicit formulas for helicity amplitudes due to $W$ boson loops are presented. It is shown that photon-photon scattering should be easily observable at PLC and separation of the $W$ loop contribution (which dominates at high energies) will be possible at $e^{+}{e}^{-}$ c.m. energy of 500~GeV or higher.
