Hello:
I have a problem and I need your help, please. I need to solve the problem 6.8 from "Quarks and Leptons. An Introductory Course in Modern Particle Physics - F.Halzem,A.Martin". It is:
Calculate the cross section for elastic scattering of unpolarized electrons from spinless point-like particles. The result is:
[tex]{d\sigma}/{dΩ}|_{Lab} = (\frac{\alpha^2}{4E^2sen^4{\vartheta/2})}) \frac{E´}{E} cos^2{\vartheta/2}[/tex]
I use as invariant amplitude:
[tex]|M|^2 = \frac{e^4}{q^4} L^{\nu\mu}_{e^-} (p+p´)_{\mu}(p+p´)_{\nu}[/tex]
Sure that I make a mistake because I am very near to the solution.
Can someone, please, tell me the name of a book in where I can see the exercise done?
Thank you.
