Chronology of Milestone Events in Particle Physics


Bridge, H.S.; de Staebler, H.C.; Rossi, B.; Sreekantan, B.V.;
Evidence for Heavy Mesons with the Decay Processes K2 ± o and K2 ± from Observations with a Multiplate Cloud Chamber
Nuovo Cim. 1 (1955) 874;

Analysis of the data on S-events observed in the M.I.T. multiplate cloud chamber shows that these events represent the decay processes of two kinds of heavy mesons. The decay processes are of two type: K2 o and K2 .
