A short overview on low mass scalars at future lepton colliders -- LCWS23 proceedings

Abstract

I give a short summary on scenarios with new physics scalars that could be investigated at future $e^{+}{e}^{-}$ colliders. I concentrate on cases where at least one of the additional scalar has a mass below 125 GeV, and discuss both models where this could be realized, as well as studies which focus on such scenarios. This work is based on arXiv:2205.09687, and partial results were also presented in arXiv:2211.10231.
