Photoproductions of dileptons, photons, and light vector mesons inp−p,p−Pb, andPb−Pbcollisions at Large Hadron Collider energies Physical Review D (IF5.296), Pub Date : 2021-10-20, DOI: 10.1103/physrevd.104.074023 Zhi-Lei Ma, Zhun Lu, Jia-Qing Zhu, Li Zhang
The photoproduction of large dileptons, photons, and light vector mesons in , , and collisions at LHC energies is studied, where the fragmentation processes and the ultra-incoherent photon channel are included. An exact treatment is developed for photoproduction processes in heavy ion collisions, which recovers the equivalent photon approximation (EPA) in the limit and can avoid double counting effectively. The full kinematical relations are also achieved. We present the results as the distributions in , , and , and the total cross sections are also estimated. The numerical results indicate that the contribution of photoproduction processes is evident in the large and regions and starts to play a fundamental role in collisions. The ultra-incoherent photon emission is an important channel of photoproduction processes, which can provide the meaningful contributions. EPA is only applicable in small and domains and is very sensitive to the values of and . The EPA errors appear when and and are rather serious in and collisions. When dealing with widely kinematical regions, the exact treatment needs to be adopted.
