Infrared Rsup(*)-operation and operator product expansion in the minimal subtraction scheme
Description
A recent generalization of Bogolubov's R-operation for subtracting a class of IR singularities (the infrared Rsup(*)-operation of Chetyrkin and Tkachov) is used to simplify considerably the calculations of the coefficient functions involved in the operator product expansion. (orig.)
