Abstract

The production of four pion events in ultraperipheral heavy-ion collisions at RHIC and LHC energies is studied. Preliminary H1 data is used to enhance the understanding of the poorly known process.  Predictions for photon-nucleus interactions are calculated for various excited states of mesons. Agreement between theoretical predictions and available STAR data at RHIC is presented.  The comparison of the four-pion invariant mass spectrum and nuclear total cross section indicates that rho(1570) plays a crucial role in accurately describing existing experimental data. Nuclear predictions for LHC energy in the central region of rapidity are also provided.
