A second light Higgs boson, with mass ≈ 140–145 GeV, is predicted by non-minimal Supersymmetric models. This new particle can account for ∼ 3σ excesses recorded by the ATLAS and CMS experiments at the Large Hadron Collider (LHC) during Run 1. We show how this can be explained in a particular realisation of these scenarios, the (B −L) Supersymmetric Model (BLSSM), which also has other captivating features, like offering an explanation for neutrino masses and releaving the small hierarchy problem of the Minimal Supersymmetric Standard Model (MSSM).
