The problem is solved. Maybe I made mistake somewhere.(I calculated hundreds times to exaggerate.) Anyway thanks for reading this annoying post(at least I think I made another trash, but more than 100 people read this)

Hi I am studying qft with worldwidely used text, written by Peskin and Schroeder, An introduction to qft. I have trouble with the calculation of thr numerator on pp. 192. I got additional term ## 2m(z-xy)(mγ^μ - p^μ) ## between spinors, which seems not vanishing. Is there any idea to treat this...

I still cannot figure out the connection between Jones vectors and my problem. Anyway thanks a lot :)

Hi, I am currently studying quantum field theory with worldwidely used text written by Peskin and Schroeder. On page 165 of that text it says, " the amplitude vanishes unless the final photon is right-handed." But I cannot figure out how it works. With ε = (0,1,i,0), I get same expression...
