Thnak you very much. You are right. I was confusing something, and your answers made me realize that. Thanks again

I have a proton and an antiproton scattering, via a pion exchange. The matrix element has the form: M=g*(\bar{u}_{1}\gamma ^{5}u_{2})\frac {1} {q^2-m^2}( \bar{v}_{1}\gamma ^{5}v_2) Wher g is my coupling constant, and q the 4-momentum of the pion. The problem is that when I compute the...
