Wormhole solution to the strongCPproblem

We show that the procedure of maximizing G^-1({α}), the inverse of Newton's constant within the wormhole calculus, subject to the constraint that the effective cosmological constant vanish, drives the QCD {θ} parameter to {θ}=0,{π} which are the CP conserving values. We argue that, in fact, {θ}={π} is the preferred value and discuss the phenomenological consistency of this choice.
