$U(1)_{T3R}$ Extension of Standard Model: A Sub-GeV Dark Matter Model
  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 $\sim
1-10$ 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 $R_{K^{(\ast)}}$ 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.
