When is a Particle?
Drell, Sidney D.
Physics Today, 31, 6, 23-32, Jun 78
Gives a new definition for the concept of the elementary particle in nuclear physics. Explains why the existance of the quark as an elementary particle could be an accepted fact even though it lacks what traditionally identifies a particle. Compares this with the development which took place during the discovery of the neutrino in the early thirties. (GA)
