Production Of Hidden-Charm And Hidden-Bottom Pentaquark States In Electron-Proton Collisions

Electro-production of several pentaquark states is investigated in this study. The eSTARlight package is adapted to study the electro-production of J/psi and Upsilon(1S) via pentaquark P-c and P-b resonance channels in ep -> eJ/psi p and ep -> e Upsilon(1S)p scattering processes at the proposed electron-ion colliders (EICs). The results obtained in this study are compared to those of non-resonance (-channels, which are described in the pomeron exchange model developed in our studies. Some pseudo-rapidity and rapidity distributions of J/psi and Upsilon(1S) are presented for the proposed EICs, including EicC and EIC-US. It is found that EicC is a good platform to identify P-b states in the future.
