Abstract: (Elsevier)
The values of d F 1 (q 2 ) d q 2 at q 2 =0 for the neutron and the proton provide a measure of the average transverse separations squared, 〈 y 2 〉, between a u or d quark and the rest of the partons in a nucleon. Using the measured values of the form factors (together with parton x -distributions), we find that 〈 y 2 = 17.4 GeV −2 for u quarks and 16.4 GeV −2 for d quarks in a proton. We speculate that the small difference between u and d quarks is caused by “quark pairing” and discuss other possible experimental signatures of quark pairing.- MOMENTUM: PARTON
