Abstract

The particle production in photon-photon (𝛾⁒𝛾) interactions present in electron-ion collisions is investigated. We present calculations for the total cross sections and event rates related to the production of light mesons [πœ‚,πœ‚β€²,𝑓 0 and 𝑓 2 ], charmonium [πœ‚ 𝑐 and πœ’ 𝑐 ], and charmoniumlike [𝑋⁑(3915), 𝑋⁑(3940), 𝑋⁑(4140), and 𝑋⁑(6900)] states, considering the Electron - Ion Collider, Electron - ion collider in China, Large Hadron electron Collider, and Future Circular Collider - electron hadron energies. Our predictions demonstrate that experimental studies of these processes are feasible and useful to constrain the properties of light mesons and quarkonium states and shed some light on the configuration of the considered charmoniumlike states.

Search for the π‘Œβ‘(2175) in the Photoproduction Cross Section Measurement of 𝛾⁒𝑝 β†’ πœ™β’πœ‹ + β’πœ‹ βˆ’ ⁒𝑝 at GlueX

Based on 334 pb βˆ’1 of photoproduction data collected with the GlueX detector at Jefferson Lab, we have measured for the first time the cross section of the exclusive reaction 𝛾+π‘β†’πœ™β‘(1020)β’πœ‹ + β’πœ‹ βˆ’ ⁒𝑝 by reconstructing the final state 𝐾 +⁒ 𝐾 βˆ’ β’πœ‹ + β’πœ‹ βˆ’ ⁒𝑝 produced with a photon beam of energies between 8.0 and 11.6 GeV. Based on the measured differential cross section, we have performed a search for the strangeoniumlike exotic candidate π‘Œβ‘(2175), recently renamed to πœ™β‘(2170). This state has been reported by different 𝑒 + ⁒𝑒 βˆ’ annihilation experiments and it is addressed here for the first time in a photoproduction experiment. We do not find evidence for this state when using the resonance parameters quoted by the Particle Data Group and provide upper limits on the photoproduction cross section. Instead, we find a structure at a mass of π‘šβ‘(πœ™β’πœ‹ + β’πœ‹ βˆ’ ) = 2.24 GeV/𝑐 2 with a statistical significance of about 5⁒𝜎. The parameters of this structure differ from those quoted by the Particle Data Group for the πœ™β‘(2170) and are consistent with a previous observation in 𝑒 + ⁒𝑒 βˆ’ annihilation. In addition, there is evidence for a second structure at 1.82 GeV/𝑐 2 .
