Three-loop vacuum integral with four-propagators using hypergeometry
《Chinese Physics C》2019年第8期33-45,共13页Zhi-Hua Gu Hai-Bin Zhang 
Supported partly by the National Natural Science Foundation of China(NNSFC)(11535002,11705045);the youth top-notch talent support program of the Hebei Province
A hypergeometric function is proposed to calculate the scalar integrals of Feynman diagrams. In this study, we verify the equivalence between the Feynman parametrization and the hypergeometric technique for the scalar...
