Scalar 1-loop Feynman integrals as meromorphic functions in space-time dimension d
The long-standing problem of representing the general massive one-loop Feynman integral as a meromorphic function of the space-time dimension d has been solved for the basis of scalar one- to four-point functions with indices one. In 2003 the solution of difference equations in the space-time dimens...
