Intrinsic Vertex Regularization and Renormalization in ϕ4 Field Theory
Zhong-Hua Wang, Han-Ying Guo
Abstract
Based upon the intrinsic relation between the divergent lower point functions and the convergent higher point ones in the renormalizable quantum field theories, we propose a new method for regularization and renormalization in QFT. As an example, we renormalize the ϕ4 theory at the one loop order by means of this method.
