# Compact extra-dimensions as solution to the strong CP problem

@article{Bezrukov2008CompactEA, title={Compact extra-dimensions as solution to the strong CP problem}, author={Fedor Bezrukov and Yannis Burnier}, journal={Physical Review D}, year={2008} }

We propose a way of a dynamical solution of the strong CP in models with compact extradimensions. To this aim we consider a one dimensional toy model for QCD, which contains a vacuum angle and a strong CP like problem. We further consider a higher dimensional theory, which has a trivial vacuum structure and which reproduces the perturbative properties of the toy model in the low-energy limit. In the weak coupling regime, where our computations are valid, we show that the vacuum structure of the…

We present a non-perturbative study of the phase diagram of SU(2) Yang-Mills theory in a five-dimensional spacetime with a compact extra dimension. The nonrenormalizable theory is regularized on an…

### Extra Dimensions and the strong CP problem.

- PhysicsPhysical review letters
- 2001

In higher dimensional theories, such as brane world models with quasilocalized non-Abelian gauge fields, the vacuum structure turns out to be trivial and the strong CP problem is absent in the models withQuasilocized gluons.

We propose a new higher-dimensional mechanism for solving the hierarchy problem. The weak scale is generated from the Planck scale through an exponential hierarchy. However, this exponential arises…

### Vacuum accumulation solution to the strong CP problem

- Physics

We suggest a solution to the strong CP problem in which there are no axions involved. The superselection rule of the \theta-vacua is dynamically lifted in such a way that an infinite number of vacua…

Reductions from odd to even dimensionalities (5 → 4 or 3 → 2), for which the effective low-energy theory contains chiral fermions, present us with a mismatch between ultraviolet and infrared…

Gauge theories embedded into higher-dimensional spaces with certain topologies acquire inductance terms, which reflect the energy cost of topological charges accumulated in the extra dimensions. We…

The one-loop fermionic contribution to the probability of an instanton transition with fermion number violation is calculated in the chiral Abelian Higgs model in 1+1 dimensions, where the fermions…

Conventional wisdom states that Newton's force law implies only four noncompact dimensions. We demonstrate that this is not necessarily true in the presence of a nonfactorizable background geometry.…

We propose a description of the vacuum in Yang-Mills theory and arrive at a physical interpretation of the pseudoparticle solution and the attendant violation of symmetries. The existence of…

We present four-dimensional gauge theories that describe physics on five-dimensional curved (warped) backgrounds, which includes bulk fields with various spins (vectors, spinors, and scalars). Field…
