Associated production of light gravitinos at future linear colliders

Abstract

We study light gravitino productions in association with a neutralino at future linear colliders in a scenario in which the lightest SUSY particle is a gravitino and the produced neutralino promptly decays into a photon and a gravitino. Comparing with the multiple goldstino scenario, we show that energy and angular distributions of the photon provide valuable information on the SUSY masses as well as the SUSY breaking.
