摘要

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