Sfermion Pair Production in Polarized and Unpolarized $\gamma \gamma$ Collisions

Abstract

We calculate total and differential cross sections for the production of sfermion pairs in photon-photon collisions, including contributions from resolved photons and arbitrary photon polarization. Sfermion production in photon collisions depends only on the sfermion mass and charge. It is thus independent of the details of the SUSY breaking mechanism, but highly sensitive to the sfermion charge. We compare the total cross sections for bremsstrahlung, beamstrahlung, and laser backscattering photons to those in $e^{+}{e}^{-}$ annihilation. We find that the total cross section at a polarized photon collider is larger than the $e^{+}{e}^{-}$ annihilation cross section up to the kinematic limit of the photon collider.
