Massive photinos: Unstable and interesting

Abstract

Massive photinos decay into a photon and a goldstino with a calculable lifetime. Cosmological arguments indicate that photinos are either eight, mγ < 30 eV or heavy, mγ > 0.3 GeV. Light photinos could provide the missing mass in the galaxy and give rise to an observable UV background. Photino searches in high-energy experiments can be affected by photino decay.
