SOLUTION TO THE STRONG CP PROBLEM WITHOUT AN AXION

We present a solution to the strong CP problem using softly broken parity invariance in the context of left-right-symmetric gauge models with a "seesaw" mechanism for quark masses. A distinguishing feature of the model is that the first nonvanishing contribution to arises only at the two-loop level, whereas the electric dipole moment of the neutron dne is generated at the one-loop level via weak CP violation. For the WR mass at the TeV scale, we estimate den 10-25-10-26 ecm and 10-12. © 1990 The American Physical Society.
