A Higgs boson at 96 GeV?!

Abstract

We briefly summarize some searches for Higgs bosons with a mass of mφ ≤ 110 GeV at LEP and the LHC. We discuss a possible signal in the diphoton decay mode at mφ ∼ 96 GeV as reported by CMS, together with a ∼ 2 σ hint in the bb final state at LEP. We briefly review possible interpretation of such a new particle in various BSM models. We focus on possible explanations as reported within the NMSSM and the µνSSM. Conclusions for future collider projects are briefly outlined.
