Exclusive four-pion photoproduction in ultra-peripheral heavy-ion collisions at RHIC and LHC energies

We study the photoproduction of exclusive \(2\pi^+2\pi^-\) mesons in ultra-peripheral heavy-ion collisions at RHIC and LHC energies. Predictions in photon-nucleus interactions are calculated for various resonances at central and forward rapidities. The recent H1 preliminary data are utilized to impr...

Description
Summary:We study the photoproduction of exclusive \(2\pi^+2\pi^-\) mesons in ultra-peripheral heavy-ion collisions at RHIC and LHC energies. Predictions in photon-nucleus interactions are calculated for various resonances at central and forward rapidities. The recent H1 preliminary data are utilized to improve the description of the poorly known \(\gamma p \to 4\pi^\pm p\) process. We present the comparisons of our results to the available STAR data at RHIC, and made predictions for LHC energies.
