Abstract

Introduction/purpose: The principal techniques of regularization schemes and their validity for gauge field theories are discussed.

Methods: Schemes of dimensional regularization, Pauli–Villars and lattice regularization are discussed.

Results: The Coleman–Mandula theorem shows which gauge theories are renormalizable.

Conclusion: Some gauge field theories are renormalizable, the Standard Model in particular.
