TL;DR

This paper investigates the spin effects in diffractive J/Ψ leptoproduction, finding that the spin-dependent cross section is weakly sensitive to the pomeron coupling structure, making experimental study challenging.

Contribution

It introduces a simple model for the pomeron-proton coupling and analyzes its impact on spin asymmetries in diffractive J/Ψ production.

Findings

Weak sensitivity of spin-dependent cross section to pomeron structure

Difficulty in studying pomeron coupling via polarized experiments

Implication for future experimental designs

Abstract

We calculate the cross section and the $A_{ll}$ asymmetry of the diffractive vector meson leptoproduction for a simple model of the pomeron coupling with the proton. It is found that the sensitivity of the spin--dependent cross section of the diffractive $J/\Psi$ production to the pomeron coupling structure is rather weak. The conclusion is made that it will be difficult to study the structure of the pomeron coupling with the proton in future polarized diffractive experiments on the $J/\Psi$ production.
