Accessing the QCD Van der Waals force with SoLID-J/ψ and beyond

ORAL

Abstract

The future SoLID-$J/\psi$ experiment at Jefferson Lab combines high luminosity with a large acceptance detector to enable a fully differential measurement of near-threshold $J/\psi$ photo- and electroproduction cross-section with high statistical precision. This measurement is sensitive to the non-perturbative gluonic interaction between the $J/\psi$ and the nucleon. This interaction could give rise to a purely gluonic binding force between both color-neutral particles: a QCD Van der Waals force between two color dipoles. I will discuss the impact of SoLID-$J/\psi$ on our understanding of this binding force and further opportunities with nuclear targets.
