Electroproduction of heavy vector mesons using holographic QCD: From near threshold to high energy regimes
Abstract
We develop a nonperturbative analysis of the electroproduction of heavy vector mesons ($$\phi$$, J/Ψ) from threshold to high energy. We use the holographic construction with bulk confinement enforced through a soft wall. Using Witten diagrams, we evaluate the pertinent cross sections for heavy vector mesons ($$\phi$$, J/Ψ) production and study their dependence on both the incoming virtual photon polarization as well as the outgoing polarization of the heavy meson. Our results for J/Ψ electroproduction compares well with the available HERA data at low and intermediate Q2, and for a wide range of momentum transfer. We also predict the quasi-electroproduction of J/Ψ near threshold.
