1. The problem statement, all variables and given/known data
b) The Large Hadron Collider (LHC), a 14 TeV proton-proton collider, will produce about a million Z0 per year. Explain why the cross section of such a process can be approximately written as:
$$d\sigma / d\Omega = F_{q/p}(X_{1})F_{q'/p}(X_{2})d\sigma '(qq' \rightarrow Z)/d\Omega$$
where
$$d\sigma '(qq' \rightarrow Z)/d\Omega$$ is the point like cross section.

2. Relevant equations
None given except as above...

3. The attempt at a solution
I can't really figure this one out at all... any points in the right direction would be greatly appreciated! Thankyou!
