Axion couplings in gauged U(1)' extensions of the Standard Model

We explore the effective theory of an axion in a gauged baryon number symmetry extension of the Standard Model (SM), where the axion is realized from a Dine-FischlerSrednicki-Zhitnitsky (DFSZ) model construction. Integrating out the anomalons realizes a pattern of effective Wilson coefficients reflecting the factorization between the anomalous Peccei-Quinn and gauged baryon number symmetries. We construct and analyze the chiral transformation invariance of the axion effective theory, accounting for possible flavorviolating axion couplings. We calculate and study the unique phenomenology of the axion and Z 0 boson, and we present the current collider limits on these particles in the {m(Z)', g(B)}, {m(alpha), G(alpha gamma gamma)}, and {m(alpha), f(-1)alpha} planes.
