Dark Sector spectroscopy at the ILC

TL;DR

This paper explores how measurements at the ILC can distinguish different dark sector models, providing insights into the structure and properties of potential dark matter candidates beyond simple detection.

Contribution

It introduces a method to discriminate between dark sector realizations using a limited set of observables at the ILC.

Findings

Few observables can differentiate dark sector models.

The spin of mediators can be inferred from collider data.

The approach enhances understanding of dark matter properties.

Abstract

Recent studies have shown that searches in the mono-photon and missing energy final state can be used to discover dark matter candidates at the ILC. While an excess in this final state over the Standard Model background would indicate the existence of a dark sector, no detailed information about the internal structure of this sector can be inferred. Here, we demonstrate how just a few observables can discriminate between various realizations of dark sectors, including e.g. the spin of mediators.
