Lorentz Covariance in Epstein-Glaser Renormalization
arXiv:hep-th/9904136
Abstract
We give explicit and inductive formulas for the construction of a Lorentz covariant renormalization in the EG approach. This automatically provides for a covariant BPHZ subtraction at totally spacelike momentum useful for massless theories.
