Abstract: (APS)

We show, by explicit construction of a highly convergent superweak theory of CP nonconservation, that the problem of natural suppression of strong P and T noninvariances—in the presence of instantons—may be resolved without invoking symmetries which imply massless quarks or nearly massless bosons.
