Cross section evaluation by spinor integration. II. The massive case in 4D

In this paper, we continue our study of calculating the cross section by the spinor method, i.e., performing the phase space integration using the spinor method. We have focused on the case where the physical momenta are massive and in pure four dimensions. We established the framework of such a new method and presented several examples, including two real progresses: Z0→l+l-H and qq→ffH0.
