Abstract
The exclusive rho , omega and J/Psi photoproduction in fixed-target collisions at the LHC is investigated. We estimate, for the first time, the rapidity and transverse momentum distributions of the vector meson photoproduction in pHe, pAr, PbHe and PbAr fixed-target collisions at the LHC using the STARlight Monte Carlo and present our results for the total cross sections. Predictions for the kinematical range probed by the LHCb detector are also presented. Our results indicate that the experimental analysis of this process in fixed-target collisions at the LHC is feasible. Such future analysis will probe the QCD dynamics in a kinematical range complementary to that studied in the collider mode.
Highlights
A complementary kinematical range can be studied in fixed-target collisions at the Large Hadron Collider (LHC)
The experimental results from Tevatron, RHIC and LHC have demonstrated that the study of hadronic physics using photon-induced interactions in pp/ p A/A A colliders is feasible and provide important information about the Quantum Chromodynamics (QCD) dynamics and vector meson production
Our analysis has been motivated by the proposition of the AFTER@LHC experiment and by the study of beam–gas interactions, recently performed by the LHCb detector
Summary
A complementary kinematical range can be studied in fixed-target collisions at the LHC. The fixed-target collisions allows to probe the photon-induced interactions in a limited energy range, dominated by low-energy interactions Such analysis can be considered as complementary to those performed in the collider mode, where the maximum energies can reach values of. Photoproduction in p A and Pb A collisions at the energies and configurations considered by the LHCb experiment Our goal in this exploratory study is to provide a first estimate of the total cross sections and associated distributions that can be measured at the LHC taking into account of some realistic experimental requirements on the final states. We postpone for a future publication a more detailed discussion about the description of the vector meson production in the soft and/or low energy regimes probed in fixed target collisions
