Graduate Peskin & Schroeder QFT 5.6 Need help
Well if I calculate a bit I get finally something like k_1\!\!\!/u_R(p_1)\bar{u}_R(k_1) and further terms of that type. What can i do with that?- philipke

Graduate Peskin & Schroeder QFT 5.6 Need help
Sorry here again the equation: \bar{u_R}(p_2)\frac{-\gamma^{\nu}k_2\!\!\!/\gamma^{\mu} + 2\gamma^{\nu}p_1^{\mu}}{-2p_1k_2}u_R(p_1) + the same term with k_1 <-> k_2 and \mu <-> \nu This is one factor in my amplitude (from the propagator). How can I apply the Fierz identity? I could...- philipke

Graduate Peskin & Schroeder QFT 5.6 Need help
Hey! I need some help for problem 5.6 (b) in Peskin + Schroeder QFT. I can't get rid of the term including three gamma matrices in my amplitude. I get two terms of the form: \frac{-\gamma^{\nu}*\slash{k_2}*\gamma^{\mu} + 2\gamma^{\nu}p_1^{\mu}}{-2*p_1*k_2} and the same with k_1 <->...- philipke
