Abstract

In my talk today, I will mainly discuss baryon resonances with emphasis on the discovery of the Ω-. However, for completeness, I will also present some data on the meson resonances which together with the baryons led to the uncovering of the SU(3) symmetry of particles, and ultimately to the concept of quarks. This period of particle physics was characterized by a strong interplay between theory and experiment. Experiments were numerous and the phenomenology kept pace with the forthcoming results. The early experimental work was performed at cyclotrons, Berkeley, Chicago, Columbia, Carnegie Tech, Rochester, etc., then moving on to the so-called doughnut machines at BNL, LBL, CERN and Cornell. The analysis of the experimental results was greatly aided by the introduction of Lee-Yang test function, Dalitz plots, the Jackson angle, the Treiman-Yang angle, etc. A consequence of this close interaction was the rapid progress in categorizing the large number of meson and baryon resonances. Furthermore, most of the early characterizations were correct; the existence and properties of resonances were validated by later experiments.
