Perturbative QCD (pQCD):<br />
Asymptotic Behavior?<br />
Q 2 F 2/F 1->1 for (very) large Q 2 (Brodsky and Farrar, 1975).<br />
Definitively not occurring yet for <strong>the</strong> proton, perhaps just starting<br />
for <strong>the</strong> neutron; what is <strong>the</strong> significance <strong>of</strong> different behavior for<br />
proton and neutron, beyond <strong>the</strong> consequence <strong>of</strong> neutrality, implying<br />
that F1n→0 for Q2 →0?<br />
