A model for fermionic dark matter addressing both the CDF $\mathbf{M_W}$ and the $\mathbf{(g-2)_\mu}$ anomalies

TL;DR

This paper proposes a renormalizable fermionic dark matter model that simultaneously explains the muon g-2 anomaly and the CDF W-boson mass measurement, involving Higgs portal interactions and extended Higgs sectors.

Contribution

It introduces a simple fermionic dark matter model addressing both the muon g-2 and W-boson mass anomalies with minimal and extended Higgs sectors.

Findings

The model can account for the observed anomalies within current experimental constraints.

Higgs portal interactions are key to the dark matter phenomenology.

Extended Higgs sectors provide additional parameter space for anomaly explanations.

Abstract

We explore a simple and renormalizable model which incorporates a new stable fermion that accounts for the dark matter in the universe and which, at the same time, provides an interpretation of two recent measurements that deviate from the expectation in the Standard Model: the muon anomalous magnetic moment and the mass of the W-boson recently performed by the CDF collaboration. The model has a fermionic sector that involves a singlet and a doublet fields and in which the lightest state is the DM and interacts mainly through the Higgs portal. Two realizations of such a possibility are considered: one in which the Higgs sector is minimal and another in which it is extended to contain two doublet fields.
