Abstract

We study the Tevatron signatures of promptly-decaying slepton co-NLSPs in the context of General Gauge Mediation (GGM). The signatures consist of trileptons plus and same-sign dileptons plus . Focusing first on electroweak production, where the Tevatron has an advantage over the early LHC, we establish four simple benchmark scenarios within the parameter space of GGM which qualitatively capture all the relevant phenomenology. We derive limits on these benchmarks from existing searches, estimate the discovery potential with 10 fb−1, and discuss ways in which these searches can be optimized for slepton co-NLSPs. We also analyze the Tevatron constraints on a scenario with light gluinos that could be discovered at the early LHC. Overall, we find that the Tevatron still has excellent reach for the discovery of SUSY in multilepton final states. Finally, we comment on the possible interpretation of a mild “excess” in the CDF same-sign dilepton search in terms of slepton co-NLSPs.
