QED, Electron-Proton Scattering: Rosenbluth cross-section

[lapantufla]

Homework Statement

In problem 8.3 of Mandl & Shaw's book "Quantum Field Theory" I have to derive the Rosenbluth cross section for the electron-proton scattering that I post on the image. I tried but I can't get to the result because the accounts are too complicated for me. Does anyone know a solution or book where they do the accounts step by step? Or perhaps someone has done this account and can post the solution?

Relevant Equations

Rosenbluth Cross-Section, Electron-Muon Feynmann amplitude. Quoted in the images

Hello, this problem is causing headaches, it would be very helpful if you could tell me if you know of a book where you can solve it. Maybe my English is lousy because I use a translator. Thank you very much.

You have to show some work first. Show your first steps and where you are stuck.
