Hypergeometric functions, their epsilon expansions and Feynman diagrams
M. Yu. Kalmykov, Bernd A. Kniehl, B. F. L. Ward +1
We review the hypergeometric function approach to Feynman diagrams. Special consideration is given to the construction of the Laurent expansion. As an illustration, we describe a c…

Pole Mass, Width, and Propagators of Unstable Fermions
Bernd A. Kniehl, Alberto Sirlin
The concepts of pole mass and width are extended to unstable fermions in the general framework of parity-nonconserving gauge theories, such as the Standard Model. In contrast with…

Simple On-Shell Renormalization Framework for the Cabibbo-Kobayashi-Maskawa Matrix
Bernd A. Kniehl, Alberto Sirlin
We present an explicit on-shell framework to renormalize the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix at the one-loop level. It is based on a novel procedure to separate…
