One of the main difficulties in studying Quantum Field Theory, in theperturbative regime, is the calculation of D-dimensional Feynman integrals. Ingeneral, one introduces the so-called Feynman parameters and associated withthem the cumbersome parametric integrals. Solving these integrals beyond theone-loop level can be a difficult task. Negative dimensional integration method(\ndim{}) is a technique whereby such problem is dramatically reduced. In thiswork we present the calculation of two-loop integrals in three diferent cases:scalar ones with three diferent masses, massless with arbitrary tensor rank,with N-insertions of a 2-loop diagram.Comment: 7 pages, 4 figures, RevTex.
