Description

Several searches for Higgs bosons below 125 GeV show an excess around $m_\phi = 95.4$ GeV. These include in particular $gg \to \phi \to \gamma\gamma$ at CMS and ATLAS and $e^+e^- \to Z^* \to Z (\phi \to b \bar b)$ at LEP. We discuss BSM Higgs sectors that can accommodate these excesses. We demonstrate that such a light Higgs boson can be analyzed in detail at $e^+e^-$ colliders.
