Abstract
Electron scattering at large Q2 probes a nucleonʹs quark core. This coreʹs contribution to electromagnetic form factors may be calculated using Poincaré covariant Faddeev amplitudes combined with a nucleon-photon vertex that automatically fulfills a Ward-Takahashi identity for on-shell nucleons. The calculated behaviour of View the MathML source on Q2∈[2,6] GeV2 agrees with that inferred from polarisation transfer data, and exhibits a zero at Q2≈6.5 GeV2. There is some evidence that F2(Q2)/F1(Q2)∝2[lnQ2/Λ2]/Q2 for Q2≳6 GeV2.
