So this is a big enough detector? That would mean they need to wait for such events to occur again and again towards this "5sigmas".
Hopefully, other aparatus elsewhere are big enough too in order to spot similar events.

What I was addressing was whether this detector is big enough for a reliable discovery. In that case what you really want to constrain is the rate, such-and-such events per kilogram of xenon per year (the per-kilogram-of-xenon can be traded for a per-liter rate given the density of the xenon).
