Production of hidden-charm and hidden-bottom pentaquark states in electron-proton collisions

Abstract

Electro-production of several pentaquark states is investigated in this paper. eSTARlight package is adapted to study the electro-production of $J/\psi$ and ${\rm Y}(1S)$ via pentaquark $P_c$ and $P_b$ resonance channels in $ep\to eeJ/\psi p$ and $ep\to e{\rm Y}(1S)p$ scattering processes at proposed electron-ion colliders (EICs). The results in this paper are compared to the non-resonance $t$-channels, which is described in pomeron exchange model in our studies. Some pseudo-rapidity distributions rapidity distributions of $J/\psi$ and ${\rm Y}(1S)$ are presented for proposed EICs including EicC and EIC-US. It is found that EicC is a good platform to identify $P_b$ states in the future.
