Planck-scale physics and solutions to the strong CP problem without the axion.
We analyse the impact of quantum gravity on the possible solutions to the strong CP problem which utilize the spontaneously broken discrete symmetries, such as parity and time reversal invariance. We find that the stability of the solution under Planck scale effects provides an upper limit on the scale Λ of relevant symmetry breaking. This result is model dependent and the bound is most restric...
متن کاملOn the Strong CP-Problem without Axion Field
In this letter we present a topological observation related to the CP problem in non-Abelian gauge theories, based on significant differences between space-times and their Wick-rotation. We point out that models containing stationary black holes the problem of CP breaking does not appear.
متن کاملA Solution to the Strong Cp - Problem in the Su (
The possibility of naturally suppressing strong CP-violation in the grand unified SU(5) model is examined. We show that a recent solution to the quark-lepton mass ratio problem by Georgi and Jarlskog can be extended in such a way as to yield a zero strong CP violating parameter 0 at the tree level and a small value for it coming from higher order effects, along with reasonable mass ratios and m...
متن کاملA Vacuum Accumulation Solution to the Strong CP Problem
We suggest a solution to the strong CP problem in which there are no axions involved. The superselection rule of the θ-vacua is dynamically lifted in such a way that an infinite number of vacua are accumulated within the phenomenologically acceptable range of θ < 10, whereas only a measure-zero set of vacua remains outside of this interval. The general prediction is the existence of membranes t...
متن کاملA Simple Solution to the Strong CP Problem
We propose a minimal modification of the standard model, remarkable in its simplicity, which may solve the strong CP problem. It employs three Higgs doublets with interactions taken to be invariant under a flavor symmetry. Both CP and the flavor symmetry are softly broken by Higgs boson mass terms. In tree approximation, quark mass matrices are triangular and arg detM vanishes. Radiative correc...
