Abstract:
A general method is proposed for calculating massive Feynman integrals on
the basis of a representation of the massive denominators in the form of
Mellin–Barnes integrals. This method is used to obtain expressions for
some classes of single-loop massive Feynman integrals of propagator and
vertex type (for arbitrary values of the powers of the denominators and
dimension of space). The results are presented in the form of hypergeometric
functions, making it possible to investigate different ranges of variation of the momenta.
