Abstract

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 ) μ 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.
