Description
A superlight (of mass ∼M/sub W/2M/sub Pl//sup -1/) gravitino may have observable consequences for high-energy reactions at the teraelectronvolt scale. Tree-level unitarity is shown to break down there for two-photon production of a pair of longitudinally polarized gravitinos. The cross section rises fast with energy and should be measurable at around 100 GeV. A double-tag search for ee-bar→ee-bar+''nothing'' will push up the lower bound on the gravitino mass or detect a superlight gravitino
