摘要:We sketch how the $R^*$-operation can be used to compute the pole terms of Feynman diagrams. As an example, we briefly discuss the computatation of the Higgs decay to gluons. Next, we illustrate how \MSbar{} counterterms can be obtained with the $R^*$-operation. Finally, we describe how the UV counterterm of any $L$-loop Feynman diagram with arbitrary local operators can be computed from $L-1$-loop massless propagator diagrams.
