Discovery of pion in 1947, Lattes, Occhialini and Powell from Bristol observed decay of a new particle into two particles one of the decay products is the muon (discovered by Neddermeyer), and the other is invisible (Pauli's neutrino). muon in turn also decays in 18
Kaons First observation of Kaons: • Experiment by Clifford Butler and George Rochester at Manchester • Cloud chamber exposed to cosmic rays • Left picture: neutral Kaon decay (1946) • Right picture: charged Kaon decay into muon and neutrino • Kaons first called “V” particles • Called “strange” because they behaved differently from others 19
