A Higgs Boson at 96 GeV?!

Abstract

We briefly summarize some searches for Higgs bosons with a mass of $m_\phi \le 110$~GeV at LEP and the LHC. We discuss a possible signal in the diphoton decay mode at $m_\phi \sim 96$~GeV as reported by CMS, together with a $\sim 2\,\sigma$ hint in the $b \bar b$ 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 \mnSSM. Conclusions for future collider projects are briefly outlined.
