QCD evolution<br />
So far ignored! Can be easily included because<br />
likewise:<br />
For t ≪ Q 2 , leading order evolution t-independent<br />
For ξ = 0 evolution kernel <strong>for</strong> GPDs same as DGLAP evolution<br />
kernel<br />
impact parameter dependent PDFs evolve such that different b ⊥<br />
do not mix (as long as ⊥ spatial resolution much smaller than Q 2 )<br />
