A Cosmological Upper Bound on Superpartner Masses
Lawrence J. Hall🇺🇸 · Joshua T. Ruderman🇺🇸 · Tomer Volansky🇮🇱
Abstract
If some superpartners were in thermal equilibrium in the early universe, and if the lightest superpartner is a cosmologically stable gravitino, then there is a powerful upper bound on the scale of the superpartner masses. Typically the bound is below tens of TeV, often much lower, and has similar parametrics to the WIMP miracle.
