Exclusive production of Tcc- in hadron-hadron ultraperipheral collisions

Understanding the production mechanisms and utilizing them as probes to investigate the structure of exotic states represent some of the most actively studied research areas in particle physics. In this study, we present a theoretical analysis of the charmed meson T-cc in the gamma p- D+T-cc Lambda+c and gamma gamma- D+T-ccD*0 reactions, considering T+cc as a DD* molecule. The differential cross section and total cross section for the photoproduction of T-cc in the gamma p- D+T-cc Lambda+c and gamma gamma- D+T-ccD*0 reactions are presented for nucleusnucleus (nucleon -nucleon) ultraperipheral collisions at HL-LHC and RHIC, respectively. Taking into account the integrated luminosity per typical run and the luminosity of photons from the nucleus (nucleon), we observe a significant event count for T-cc production in p -p ultraperipheral collisions at HL-LHC.
