Electroproduction of heavy quarkonia: significance of dipole orientation
Original language description
The differential cross section dσ/dq2 of diffractive electroproduction of heavy quarkonia on protons is a sensitive study tool for the interaction dynamics within the dipole representation. Knowledge of the transverse momentum transfer q-> provides a unique opportunity to identify the reaction plane, due to a strong correlation between the directions of q-> and impact parameter b->. On top of that, the elastic dipole-proton amplitude is subject to a strong correlation between b-> and dipole orientation r->. Most of models for b-dependent dipole cross sections either completely miss this information, or make unjustified assumptions. We perform calculations basing on a realistic model for r->-b-> correlation, which significantly affect the q dependence of the cross section, in particular the ratio of ψ'(2S) to J/ψ(1S) yields. We rely on realistic potential models for the heavy quarkonium wave function and the Lorentz-boosted Schrödinger equation.
