thank you blechman , in that paper it was given the formula of the vertex of three photons where the initial state is the vacuum (|i>=|0>) and the final state |f> is three photons,and this case in not present in compton scattering,where we have in the initial state one photon (or two photon)...

Non Commutative Cross-Section hello, this is my first post here, i have searched the web but i didnt find what i am looking for,so i hope i find it here. i am looking for the formula of the cross section of compton scattring in the non commutative space-time .
