Invariance Principles and Elementary Particles

J. J. Sakurai''s treatment of various elementary particle phenomena, is written for those not completely familiar with field theory who wish to gain insight into theoretical problems. Since the manuscript for his book was completed, a very important development has taken place in particle physics-the discovery of the p, w, and n mesons: in view of this development, the author has added a new section devoted exclusively to these new mesons and resonances.

Originally published in 1964.
