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 <-> k_2 and \nu <-> \mu.
How can I evaluate the first term in the numerator using the Fierz identiy from 5.3?
Thanks in advance!
Philip
