Note: F 1p d ~ F2p u ~ -F2p d at<br />

Q 2 < 3.5 GeV 2 (current limit<br />

for complete data base)<br />

Is this new physics, or just<br />

ano<strong>the</strong>r representation <strong>of</strong> <strong>the</strong><br />

FF <strong>of</strong> <strong>the</strong> nucleons?<br />

Or, is this more than a<br />

ano<strong>the</strong>r linear transformation<br />

between <strong>the</strong> nucleon F-form<br />

factors, similar to <strong>the</strong> one<br />

between <strong>the</strong> F 1 and F 2 and G E<br />

and G M?<br />

at Q 2 =0<br />
