Description
The dark matter experiment XENON1T reported recently an excess in electronic recoil events with a significance of 3.5 $\sigma$. Also, the Muon g-2 experiment at FERMILAB has confirmed the muon magnetic moment anomaly, raising the significance to 4.2 $\sigma$. Motivated by these experimental results, we interpret the signals in terms of a new light $Z ^\prime$ gauge boson. We discuss how such a light $Z ^\prime$ emerges in a Two Higgs Doublet Model augmented by an abelian gauge symmetry, in agreement with existing bounds.
