A short overview on low mass scalars at future lepton colliders

Abstract

In this manuscript, 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 several overview talks I recently gave at the CEPC workshop, FCC week and ECFA future collider workshop, as well as a Snowmass White Paper.
