Dark matter from one-flavor SU(2) gauge theory

TL;DR

This paper explores a minimal SU(2) gauge theory with one fermion as a candidate for dark matter, presenting preliminary lattice results and discussing implications for dark matter stability and phenomenology.

Contribution

It introduces a minimal one-flavor SU(2) gauge theory as a novel dark matter candidate and provides initial lattice simulation results.

Findings

Preliminary lattice results support the viability of the model.

Single-flavor structure naturally stabilizes dark matter.

Implications for dark matter phenomenology are discussed.

Abstract

SU(2) gauge theory with a single fermion in the fundamental representation is a minimal non-Abelian candidate for the dark matter sector, which is presently missing from the standard model. Having only a single flavor provides a natural mechanism for stabilizing dark matter on cosmological timescales. Preliminary lattice results are presented and discussed in the context of dark matter phenomenology.
