摘要：

A natural axion-free solution of the strong CP problem at tree level is noted within an E(6) grand unified theory. Using this as a springboard, it is shown that several flipped SU(5) theories which occur in superstring phenomenology contain within them a mechanism which enforces =0 at high accuracy. © 1990 The American Physical Society.
