[ExI] Has dark matter been discovered?

[John Clark]

In yesterday's Physical Review Letters an article was published that says
Dark Matter *MIGHT* have been discovered in the XENON1T underground
detector deep below the Gran Sasso mountain in Italy. The signal is less
than the five Sigma needed to claim a discovery but it was strong enough to
cause a great deal of excitement, 5 theoretical papers have already been
published to try to explain it. It might turn out to be revolutionary or it
might turn out to be nothing, we'll just have to wait and see.
