A simple connection between v(v-bar)-nucleon scattering and F1n/F1p
Description
Using the helicity conservation rule of PQCD it is shown that at large q2 various ratios involving differences of CC and NC differential cross-sections depend on the ratio F1n(q2)/F1p(q2). This form factor ratio is expected to be q2 independent in PQCD as well as from QCD sum rules. Using input from QCD sum rules possible ranges of the various cross-section ratios are predicted.
