Singlet scalars as dark matter and the muon (g-2) anomaly

We explore a simple model containing two singlet scalars as dark matter candidates and a vector-like lepton. Evading collider and dark matter constraints, the model is able to accommodate the correct dark matter relic abundance and the (g - 2)(mu) 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.

Automated summary

In this study, a simple model with two singlet scalar dark matter candidates and a vector-like lepton was explored. The model can accommodate the correct dark matter relic abundance and the (g - 2)(mu) anomaly by having the masses of the three new fields around 100 GeV and the values of the minimum required couplings being order one, while evading collider and dark matter constraints.
