主　　题：pentaquark electroproduction Pomeron electron-ion collider 

摘      要：In this study,we analyze the electroproduction of the LHCb pentaquark states with the assumption that they are resonant *** main concern is to investigate the final state distribution in the phase space to extract a feeble pentaquark signal from a large non-resonant *** results indicate that the signal to background ratio will increase significantly with a proper kinematic cut,which will be beneficial for future experimental analysis.
