Solution of the strong CP problem by color exchange.
In this Letter we propose a new way of solving the strong CP problem. ' The two key ingredients of our approach are that (I) CP invariance is spontaneously broken, and (2) light colored scalar fields mediate the CP-nonconserving interaction. One of us (A.Z.) proposed recently the introduction into the standard SU(3) S SU(2) II U(1) theory of an SU(2)-singlet scalar field X, thus allowing Yukawa...
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 کاملSimple supersymmetric solution to the strong CP problem.
It is shown that the minimal supersymmetric left-right model can provide a natural solution to the strong CP problem without the need for an axion, nor any additional symmetries beyond supersymmetry and parity. Quantum chromodynamics, which is extremely succesful in describing strongly interacting phenomena both in the low as well as the high energy domain, has the well-known problem that it ca...
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...
