Abstract

We present a class of gauge models where the phase angle associated with a parameter that breaks a U(1) global symmetry softly receives no renormalization correction due to quantum effects. As application of this idea, we consider recently proposed solutions to the strong-CP problem using softly broken Peccei-Quinn symmetry and clarify the conditions under which it works. We also extend our discussion to some new models.

Softly Broken Supersymmetric Desert from Orbifold Compactification

Journal Article Barbieri, Riccardo; Hall, Lawrence; Nomura, Yasunori - Physical Review D

A new viewpoint for the gauge hierarchy problem is proposed: compactification at a large scale, 1/R, leads to a low energy effective theory with supersymmetry softly broken at a much lower scale, \alpha/R. The hierarchy is induced by an extremely small angle \alpha which appears in the orbifold compactification boundary conditions. The same orbifold boundary conditions break Peccei-Quinn symmetry, leading to a new solution to the \mu problem. Explicit 5d theories are constructed with gauge groups SU(3) \times SU(2) \times U(1) and SU(5), with matter in the bulk or on the brane, which lead to the (next-to) minimal supersymmetric standardmore »« less

Strongly broken Peccei-Quinn symmetry in the early Universe

Journal Article Takahashi, Fuminobu; Yamada, Masaki - Journal of Cosmology and Astroparticle Physics

We consider QCD axion models where the Peccei-Quinn symmetry is badly broken by a larger amount in the past than in the present, in order to avoid the axion isocurvature problem. Specifically we study supersymmetric axion models where the Peccei-Quinn symmetry is dynamically broken by either hidden gauge interactions or the SU(3){sub c} strong interactions whose dynamical scales are temporarily enhanced by the dynamics of flat directions. The former scenario predicts a large amount of self-interacting dark radiation as the hidden gauge symmetry is weakly coupled in the present Universe. We also show that the observed amount of baryon asymmetrymore »« less

A solution of the strong CP problem via the Peccei-Quinn mechanism through the Nieh-Yan modified gravity and cosmological implications

Journal Article Lattanzi, Massimiliano; Mercuri, Simone - Physical Review. D, Particles Fields

By identifying the recently introduced Barbero-Immirzi field with the QCD axion, the strong CP problem can be solved through the Peccei-Quinn mechanism. A specific energy scale for the Peccei-Quinn symmetry breaking is naturally predicted by this model. This provides a complete dynamical setting to evaluate the contribution of such an axion to the cold dark matter content of the Universe. Furthermore, a tight upper bound on the tensor-to-scalar ratio production of primordial gravitational waves can be fixed, representing a strong experimental test for this model.

Comment on the Peccei-Quinn symmetry

Journal Article Wyler, D - Phys. Rev. D; (United States)

It is shown that the U(1) symmetry of Peccei and Quinn leads to vanishing strong CP violation even if chiral symmetry is spontaneously broken by the strong interactions.
