Description

The exclusive photo- and electroproduction of the light vector mesons $\rho ,\omega \text{and }\varphi$ are studied within the color dipole picture as function of the center-of-mass energy of the $\gamma p$ collision and the momentum transfer squared $|t|$. The corresponding vector meson wave functions have been computed with the relativistic AdS/QCD holographic approach. This enabled us to obtain a good description of all available data for the ground-state light mesons $\rho (1S),\omega (1S),\text{and }\varphi (1S)$ as well as to make predictions for the excited states $\rho (2S),\omega (2S),\text{and }\varphi (2S)$ with the same formalism. This study revealed the existence of a sizeable theoretical uncertainty coming from modeling the partial dipole amplitude in the non-perturbative kinematical domain. These uncertainties could be deeply investigated with measurements of the light vector meson cross sections in future hadron colliders.
