CALCULATION OF LOOP INTEGRALS BY DIMENSIONAL COUNTING

In the framework of dimensional regularization, a new method is propos ed for calculating loop integrals on the basis of the analytic propert ies of these integrals. In this regularization, the results are repres ented by generalized hypergeometric series. The method makes it possib le to relate the expansion coefficients of these series to the origina l integral. Such a representation of the coefficients greatly simplifi es the calculations even in the case of multiloop integrals with any n umber of masses.
