Recently, a new method of J/psi(gamma) production at the EIC has been proposed to extract poorly known color-octet NRQCD long-distance matrix elements. The proposed method involves comparison to open heavy-quark pair production and two alternative methods are also suggested.
Recently unpolarized and polarized J/psi(gamma) production at the Electron-Ion Collider (EIC) has been proposed as a new way to extract two poorly known color-octet NRQCD long-distance matrix elements: < 0 vertical bar O-8(J)/psi(S-1(0))vertical bar 0 > and < 0 vertical bar O-8(J)/psi(P-3(0))vertical bar 0 >. The proposed method is based on a comparison to open heavy-quark pair production ideally performed at the same kinematics. In this paper we analyze this proposal in more detail and provide predictions for the EIC based on the available determinations of the color-octet matrix elements. We also propose two additional methods that do not require comparison to open heavy-quark pair production.
