Sensitivity of pQCD deuteron structure to the nucleon form factors

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We discuss the applicability of pQCD to the elastic scattering of electrons on protons and deuterons. We analyze the Q2Q^2-dependence of the reduced deuteron form factor, taking into account the recent data on the electric proton form factor and we find that the value of the QCD-scale parameter Λ\Lambda differs essentially from the value Λ=0.1\Lambda=0.1 GeV, previously found using the dipole parametrization of the electromagnetic nucleon form factors GEG_E and GMG_M. Moreover the predicted scaling behavior of the reduced deuteron form factor can not be recovered in the Dirac and Pauli representations for the nucleon electromagnetic form factors.
