A particle physics private eye takes on the great interaction caper

MINERvA was starting to lose her cool. Of all the detectors in all the world, this proton walked into her’s.

After 23 hours of interrogating this proton about what he was doing at the time of the boson exchange, he wasn’t revealing sign one The had detector picked up the proton in the vicinity of the incident. His usual accomplice, the muon, was seen fleeing north, where he was apprehended by MINOS, the adjacent detector. Even with the proton refusing to talk, the greenest rookie could spot a muon and a proton in the final state and tell you this was a case of charged-current quasi-elastic neutrino scattering.
