Description

Several searches for Higgs bosons below 125 GeV show an excess around $m_{\varphi }=95.4$ GeV. These include in particular $gg\to \varphi \to \gamma \gamma$ at CMS and ATLAS and $e^{+}{e}^{-}\to Z^{\ast }\to Z(\varphi \to b\overline{b})$ 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.
