My assumption is that they are definitely not muons. ;) (Note that there are 1e13 of these things per laser pulse, whatever they are -- quite a few.) Needless to say, if the particles end up being resolved to baryons, we're dealing with energies that correspond to nuclear reactions. Another possibility, of course, is a bad experimental procedure that is not revealing a piece of equipment that is on the fritz. Eric
