Elementary particles

SEP 01, 1969

Two complementary approaches to strong‐interaction theory, the multiperipheral bootstrap and the dual‐resonance models, appear to be the most promising ways ahead. The idea that emerges is that particles hitherto thought to be “elementary” might instead be composite, all made up of bound states of each other.

THE THEORY OF STRONG INTERACTIONS has been for many years particularly hard and fruitless. Today, under the momentum of a number of new ideas, theorists in this field appear to have regained confidence and enthusiasm. Both in its mathematical tools and physical ideas, the new trend in strong interactions points to a decisive change from the old one. Is elementary‐particle theory undergoing a revolutionary change too?
