How to preserve symmetries with cut-off regularized integrals?
T. Varin, D. Davesne, M. Oertel, M. Urban
Abstract
We present a prescription to calculate the quadratic and logarithmic divergent parts of several integrals employing a cutoff in a coherent way, i.e. in total agreement with symmetry requirements. As examples we consider one-loop Ward identities for QED and a phenomenological chiral model.
