Abstract:
By using the Lorentz invariable coupling model of interaction between neutral meson and nucleon (antinucleon), Feynman convergence integral method is often used to deal with the finite quantity of one-loop correction scheme. On the basis of analyzing, discussing and researching the method, a new method is found. That is the large momentum integral limitation method. With the effective method, we obtain the integral convergence formulation for the finite quantity, by deducting-dimensionally calculating the finite quantity gained after renormalizing the meson loop propagator.
