The Q²-dependence of the Generalised Gerasimov-Drell-Hearn Integral for the Proton
read the original abstract
The dependence on Q^2 (the negative square of the 4-momentum of the exchanged virtual photon) of the generalised Gerasimov-Drell-Hearn integral for the proton has been measured in the range 1.2 GeV^2 < Q^2 < 12 GeV^2 by scattering longitudinally polarised positrons on a longitudinally polarised hydrogen gas target. The contributions of the nucleon-resonance and deep-inelastic regions to this integral have been evaluated separately. The latter has been found to dominate for Q^2 > 3 GeV^2, while both contributions are important at low Q^2. The total integral shows no significant deviation from a 1/Q^2 behaviour in the measured Q^2 range, and thus no sign of large effects due to either nucleon-resonance excitations or non-leading twist.

Insight on confinement from the QCD effective charge
Assigning the imaginary poles of α_g1 to parton propagators produces long-distance damping e^{-Λ_s|x|/√2}|x|^{-5/2+d_a}, interpreting confinement as Green's-function suppression.

Extraction of $\sigma_{TT}$ for Proton, Neutron, Deuteron and $^3$He from Quasi-real Photon Scattering
Quasi-real electroproduction data extrapolated to Q²=0 give σ_TT for p, n, d and ³He, with larger neutron/deuteron Δ(1232) strength than real-photon data and better isospin consistency.
