New Collider Bound on Light Gravitino Mass
Duane A. Dicus, S. Nandi
Abstract
In supergravity theories with a very light gravitino, the gluino decays dominantly to a gluon and a gravitino. This results in a much larger missing ET for the multijet final states in hadronic colliders. We use the latest Tevatron data for the multijet final states to set a new absolute lower bound of 3.0 x 10-13 GeV for the light gravitino mass.
