Homework Statement
In fact this is not homework, I'm self-studying QFT by reading Peskin's book, and I'm stuck with Problem 6.2.
Homework Equations
In part (e), I cannot get the factor (1+(1-x)2)/x in the cross section.
The Attempt at a Solution
Maybe I'd already been wrong in earlier parts, the result I got in part (b) is C~D~[tex]\sqrt{EE'}\theta[/tex],
and the probability I got in part (c) is ~ [tex]\frac{1}{EE'\theta^2}[/tex]
Generally I just do every problem on this book, but now I'm stuck and can't move on, please please help. Thank you.
