TL;DR
This paper investigates how future linear colliders can produce light gravitinos alongside neutralinos, analyzing photon distributions to extract information on SUSY particles and breaking mechanisms.
Contribution
It introduces a method to distinguish SUSY breaking scenarios by studying photon energy and angular distributions in gravitino-neutralino production.
Findings
Photon distributions reveal SUSY mass information.
Energy and angular data differentiate SUSY breaking scenarios.
Results support collider-based SUSY investigations.
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.
