Exclusive heavy vector meson electroproduction to NLO in collinear factorisation

Abstract

We compute the exclusive electroproduction, ${\gamma }^{\ast }p\to Vp$, of heavy quarkonia $V$ to NLO in the collinear factorisation scheme, which has been formally proven for this process. The inclusion of an off-shell virtuality $Q^2$ carried by the photon extends the photoproduction phase space of the exclusive heavy quarkonia observable to electroproduction kinematics. This process is relevant for diffractive scattering at HERA and the upcoming EIC, as well as at the proposed LHeC and FCC.
