Light Sparticles from a Light Singlet in Gauge Mediation
arXiv:1502.05836 · doi:10.1103/PhysRevD.92.015006
Abstract
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-like Higgs 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.
