Pi Day


K2K neutrino event at Super-Kamiokande reconstructed as a pi-zero.

Pi-zero decays to two gammas which make two electron-like rings. Color is time-of-flight subtracted time when light arrived at the photo detector.

This is where the "action" is - the "crime" scene of the neutrino event illustrated above. :-) Yes, you see a boat.
