Abstract
Abelian quiver gauge theories provide non-supersymmetric candidates for the conformality approach to physics beyond the standard model. Written as N=0, U(N)n gauge theories, however, they have mixed U(1)pU(1)q2 and U(1)pSU(N)q2 triangle anomalies. It is shown how to construct explicitly a compensatory term ÎLcomp which restores gauge invariance of Leff=L+ÎLcomp under U(N)n. It can lead to a negative contribution to the U(1)β-function and hence to one-loop conformality at high energy for all dimensionless couplings.
