Sfermion production at photon colliders

Abstract

We calculate total and differential cross sections for sfermion production in $e^{+}{e}^{-}$ annihilation and in photon-photon collisions with arbitrary photon polarization. The total cross section at a polarized photon collider is shown to be larger than the $e^{+}{e}^{-}$ annihilation cross section up to the kinematic limit of the photon collider.
