摘要
An explicit example is presented (a one-loop triangle graph) where dimensional regularization fails to regulate the infra-red singularities that emerge at intermediate steps of studying large- Sudakov factorization. The mathematical nature of the phenomenon is explained within the framework of the theory of the -operation.
