Chiral models of composite axions and accidental Peccei-Quinn symmetry

Chiral models of composite axions and accidental Peccei-Quinn symmetry

Abstract We introduce a class of composite axion models that provide a natural solution to the strong CP problem, and possibly account for the observed dark matter abundance. The QCD axion arises as a composite Nambu-Goldstone boson (NGB) from the dynamics of a chiral gauge theory with a strongly-in...
