Title: Hints of Light New Physics at XENON1T Experiment
The dark matter experiment XENON1T reported recently an excess
in electronic recoil events with a significance of 3.3 $\sigma$.
Motivated by this experimental result, in this talk we discuss the
interpretation of the signal not in terms of a dark matter particle, but
rather in terms of a new light $Z ^\prime$ gauge boson. We discuss how
such a light mediator emerges in a popular SM extension, in agreement
with existing bounds.
