Two-loop RG functions of the massive field theory in general dimensions
arXiv:0912.0672
Abstract
Two-loop Feynman integrals of the massive field theory are explicitly obtained for generic space dimensions . Corresponding renormalization-group functions are expressed in a compact form in terms of Gauss hypergeometric functions. A number of interesting and useful relations is given for these integrals as well as for several special mathematical functions and constants.
