Singlet Scalars as Dark Matter and the Muon g-2 Anomaly

TL;DR

This paper proposes a minimal model with two singlet scalars and a vector-like lepton that explains dark matter and the muon g-2 anomaly simultaneously, fitting current experimental constraints.

Contribution

It introduces a simple, viable model with new particles around 100 GeV that accounts for dark matter and muon g-2, consistent with collider and dark matter constraints.

Findings

Model explains dark matter relic abundance

Model accounts for muon g-2 anomaly

New particles around 100 GeV with order-one couplings

Abstract

We explore a simple model containing two singlet scalars as dark matter supplemented with a vector-like lepton. Evading collider and dark matter constraints, the model is able to accommodate the correct dark matter relic abundance and the muon g-2 anomaly when the masses of the three new fields are around 100 GeV and the values of the minimum amount of required couplings are order one.
