چکیده
|
We present several models where the qcd axion arises accidentally. confining gauge theories can generate axion candidates whose properties are uniquely determined by the quantum numbers of the new fermions under the standard model. the peccei-quinn symmetry can emerge accidentally if the gauge theory is chiral. we generalise previous constructions in a unified framework. in some cases these models can be understood as the deconstruction of 5-dimensional gauge theories where the peccei-quinn symmetry is protected by locality but more general constructions are possible.
