Symmetries as a guide to regularization ambiguities: Standard and Beyond Standard Model examples
=== This thesis is about regularization of ultraviolet divergences appearing in the perturbative expansion of quantum field theories (QFTs). We present a general view of the ambiguities that may arise in the regularization program and develop a systematic approach to extract them from a general Fey...
