An algorithm for the poles at dimension four in the dimensional regularization procedure
One-loop Feynman diagrams, when regularized using the continuous dimension method, exhibit single poles at n=4, and these poles can be eliminated by a counterterm Delta L in the Lagrangian. In this paper a simple algorithm is derived to express Delta L in terms of the components of the Lagrangian L...
