Extended scalar sectors at current and future colliders

TL;DR

This paper discusses the potential for discovering extended scalar sectors beyond the Standard Model at current and future collider experiments, following the discovery of the Higgs boson.

Contribution

It analyzes the prospects and implications of detecting additional scalar particles that extend the Standard Model's scalar sector at collider facilities.

Findings

Extended scalar sectors could be observable at future colliders.

Additional scalar states may explain phenomena beyond the Standard Model.

Current colliders have limited but promising sensitivity to new scalars.

Abstract

After the discovery of a particle that complies with the properties of the Higgs boson predicted by the Standard Model, particle physics has entered an exciting era. One important question is whether the scalar sector realized by Nature indeed corresponds to the one predicted by the SM, or whether the resonance at 125 GeV is a manifestation of a more extended scalar sector, and additional scalar states could be observed at current or future collider facilities.
