Universal definition of the non-conformal trace anomaly
Ferrero, R.; Franchino-Vinas, S.; Frob, M. B.; Lima, W. C. C.
We show that there exists a generalized, universal notion of the trace anomaly for theories which are not conformally invariant at the classical level. The definition is suitable for any regularization scheme and clearly states to what extent the classical equations of motion should be used, thus resolving existing controversies surrounding previous proposals. Additionally, we exhibit the link between our definition of the anomaly and the functional Jacobian arising from a Weyl transformation.
