Dark atoms and composite dark matter

TL;DR

This paper reviews the theoretical aspects and observational constraints of dark atoms and composite dark matter candidates, including dark glueballs, glueballinos, mesons, and baryons, focusing on cosmological and detection limits.

Contribution

It provides a comprehensive overview of the current theoretical models and observational constraints related to composite dark matter and dark atoms.

Findings

Dark atoms and composite dark matter are constrained by cosmological data.

Detection experiments limit the parameter space of dark glueballs and related particles.

Theoretical models must account for observational limits on dark matter interactions.

Abstract

I selectively review the theoretical properties and observational limits pertaining to dark atoms, as well as composite dark matter candidates bound by a confining gauge interaction: dark glueballs, glueballinos, mesons and baryons. Emphasis is given to cosmological, direct and indirect detection constraints.
