Great answer! Thanks.

Consider the process e^-\rightarrow e^-\gamma depicted in the following Feynman diagram. The spin-averaged amplitude with linearly polarised photons is \overline{|M|^2}=8\pi\alpha\left(-g^{\mu\nu}+\epsilon^\mu_+\epsilon^\nu_-+\epsilon^\mu_-\epsilon^\nu_+\right)\left(p_\mu p^\prime_\nu+p_\nu...

Do you have any reference where it is explicitly shown how to acquire that specific form of the cross section and the equivalence of the two definitions of the hadronic tensor? As for the matrix element, I find the exact same result.

I am currently following R.K. Ellis et al.: QCD and Collider Physics, pp. 99 to understand how to arrive at the parton density functions starting from the matrix elements in electron-proton deep inelastic scattering (see figure below). But there seems to be a very fundamental concept that I...

Dear all, I am new to this forum and I am looking forward to having revealing discussions with you on here. My name is Thomas, I am 25 years old and currently writing my master thesis 'Parton Density Functions for Heavy Gauge Bosons and the Higgs' at DESY Hamburg. My field of interest is...
