Do you mean Pi0 Proton -> Pi0 Proton in ChPT ?

And do you need to calculate it or just look it up?

In the former case, I can't help you beyound leading order. I have only
looked briefly at implementing baryonic ChPT. If you feel like doing it,
it would be most welcome :-) The leading order calculation is at:

In the latter case, depending on to which accuracy and how elaborate you
need the calculation, there are a variety of references. Look for
Meissner+Fettes, Mojzis or Becher+Leutwyler in
