Chargino Production and Decay in Photon-Photon-Collisions

High Energy Physics - Phenomenology 2009-10-31 v1

Abstract

We study the production and leptonic decay of charginos in collisions of polarized photon beams including the complete spin correlations. The photons can be generated by Compton backscattering of polarized laser pulses off a polarized electron beam. Since the production process is determined alone by the electromagnetic coupling of the charginos this process allows to study their decay dynamics. The cross section and the forward-backward asymmetry of the decay lepton are very sensitive to the gaugino mass parameter M1M_1 and to the sneutrino mass without any ambiguities.
