Abstract

Although many suggestions for BSM searches at future colliders exist, most of them concentrate on additional scalars that have masses higher than the current SM scalar mass. I will give a short overview on the current status of models and searches for scalars with masses below this. This work is mainly based on arXiv:2203.08210, arXiv:2205.09687.
