Abstract
In the aspon model solution of the strong CP problem, there is a gauged U(1) symmetry, spontaneously broken by the same vacuum expectation value which breaks CP, whose massive gauge boson provides an additional mechanism of weak CP violation. We calculate the CP asymmetries in B decays for the aspon model and show that they are typically smaller than those predicted from the standard model. A linear relation between the CP asymmetries of different decay processes is obtained.
