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...
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 <->...
