Light Sparticles from a Light Singlet in Gauge Mediation

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