Description

I analyze the role of Lorentz symmetry in the perturbative non-gravitational anomalies for a single family of fermions. The theory is assumed to be translational invariant, power-counting renormalizable and based on a local action, but is allowed to have general Lorentz violating operators, including those that break CPT. I study the conservation of global and gauge currents associated with general internal symmetry groups and find that Lorentz symmetry does not participate in the clash of symmetries that leads to the anomalies.
