Light axions with large hadronic couplings
Abstract We present models in which axions have large couplings to hadrons while remaining naturally light. By assigning U(1) PQ charges to Standard Model quarks such that U(1) PQ is not anomalous under QCD, the derivative couplings naturally arise while no potential is generated for the axion upon...
