pQCD phenomenology of elastic ed scattering

Abstract

Electron-deuteron elastic scattering data ($A(Q^2)$ and $B(Q^2)$ structure functions and polarization observables $t_{20}$, $t_{21}$ and $t_{22}$) are fit with a model that respects asymptotic properties of pQCD at high momentum transfer. The data analysis shows that pQCD starts from $Q^2=3.5 \rm (GeV/c)^2$. Predictions for the magnetic structure function $B(Q^2)$ and the polarization observables at high momentum transfer are given.
