Low mass scalars at $e^{+}{e}^{-}$ colliders

Abstract

I briefly discuss the search for low mass scalars at Higgs factories as well as available models that render such scalars feasible, where I focus on new developments since the review presented in arXiv:2205.09687 (see also arXiv:2504.11969 for a recent update).
