- Title
Grand unification and heavy axion.
- Authors
Rubakov, V. A.
- Abstract
We argue that sufficiently complex grand unified theories involving extra strong intractions that confine at very short distances may lead to a heavy axion solution of the CP problem of QCD. This axion may have a mass within the accessible energy range, and its low-energy interactions emerge through mixing with axial Higgs boson(s). Another signature of this scenario is softly broken Peccei–Quinn symmetry in the electroweak Higgs sector. We present a toy GUT exhibiting these features. © 1997 American Institute of Physics.
