Abstract

We present a model based on a U(1)_T3R extension of the Standard Model. The model addresses the mass hierarchy between the third generation and the first two generation fermions. U(1)_T3R is spontaneously broken at ∼ 1-10 GeV. The model contains a sub-GeV dark matter candidate and two sub-GeV light scalar and vector mediators. The model explains the thermal dark matter abundance, measurements of the muon g-2 and R_K^(∗) anomalies. The model can be probed at the LHC, FASER, dark matter experiments and various beam-dump based neutrino facilities, e.g., COHERENT, CCM, MicroBooNE, SBND, ICARUS, DUNE etc.
