Selectron NLSP in Gauge Mediation

Understand

We discuss gauge mediation models in which the smuon and the selectron are mass-degenerate co-NLSP, which we, for brevity, refer to as selectron NLSP.

• In these models, the stau, as well as the other superpartners, are parametrically heavier than the NLSP.
• We start by taking a bottom-up perspective and investigate the conditions under which selectron NLSP spectra can be realized in the MSSM.
• We then give a complete characterization of gauge mediation models realizing such spectra at low energies.
