An extra-dimensional axion in a 5D warped orbifold GUT
Abstract We study the QCD axion arising from the 5th component of a bulk U(1) gauge field in a five-dimensional warped grand unified theory, and determine the viable range of the axion decay constant f a . Unlike flat extra dimensions, where gauge couplings run quickly above the Kaluza-Klein (KK) sc...
