Can the Axions of Standard-like Superstring Models solve the Strong CP problem?
Description
We find that there are three axions in standard-like superstring models in the four dimensional free fermionic formulation. These axions are either harmful or very heavy. Therefore they cannot solve the strong CP problem. We show that this is a general results in superstring models with chiral generation from the Z2 twisted sectors which use a Z4 twist (author)
