Dark Matter, Muon Anomalous Magnetic Moment and the XENON1T Excess

TL;DR

This paper proposes a minimal extension to the Standard Model with three scalar fields to simultaneously explain the muon magnetic moment anomaly, dark matter relic abundance, and the Xenon-1T excess via inelastic dark scalar scattering.

Contribution

It introduces a simple scalar extension that unifies explanations for multiple anomalies and experimental observations in particle physics and cosmology.

Findings

Successfully accounts for muon g-2 anomaly

Reproduces dark matter relic abundance

Explains Xenon-1T excess through inelastic scattering

Abstract

A very economic scenario with just three extra scalar fields beyond the Standard Model is invoked to explain the muon anomalous magnetic moment, the requisite relic abundance of dark matter as well as the Xenon-1T excess through the inelastic down-scattering of the dark scalar.
