Light Sparticles from a Light Singlet in Gauge Mediation

We revisit a simple model that combines minimal gauge mediation and the next-to-minimal supersymmetric standard model. We show that one can obtain a 125 GeV Standard Model-likeHiggs boson with stops as light as 1.1 TeV, thanks to the mixing of the Higgs with a singlet state at O (90 - 100) GeV. Sparticle searches at the LHC may come with additional b-jets or taus and may involve displaced vertices. The sparticle production cross-section at the 13 TeV LHC can be O (10 - 100) fb, leading to great prospects for discovery in the early phase of LHC Run II.
