Abstract
We propose a new method to calculate the 4-dimensional divergent integ rals. By calculating the one-loop integral as an example, the regulari zation of he integrals in 3-dimension momentum space is given in detai l. We find that the new method gives the same results as the tradition al dimensional regularization method,but it has the advantage of givin g the real and tile imaginary part separately.
