Summary
English: The world's first neutrino observation in a hydrogen bubble chamber was found Nov. 13, 1970, on this historical photograph from the Zero Gradient Synchrotron's 12-foot bubble chamber. The invisible neutrino strikes a proton where three particle tracks originate (right). The neutrino turns into a muon, the long center track. The short track is the proton. The third track is a pi-meson created by the collision.
Français : Photographie historique de la première observation d'un neutrino dans une chambre à bulles d'hydrogène de 12 pieds (3,70 m.) du Zero Gradient Synchrotron, prise le 13 novembre 1970. Sur cette image, un neutrino invisible percute un proton, donnant naissance aux traces des particules résultant de la collision sur la droite de l'image : le neutrino se transforme en méson-mu (longue trace rectiligne centrale). La trace la plus courte au-dessus matérialise le chemin parcouru par le proton. La troisième trace est celle d'un méson-pi créé par la collision.
