Abstract

We study the cross sections for the electro-production of Pc(4312)P_c(4312) particle, a recently discovered pentaquark state, in electron-proton collisions assuming possible quantum numbers to be JP=12±,32±J^{P}=\frac{1}{2}^\pm, \frac{3}{2}^\pm. s\sqrt{s} is set to the energy of the future Electron Ion Collider at Brookhaven National Laboratory, in order to asses the possibility of the measurement in this facility. One can discriminate the spin of Pc(4312)P_c(4312) by comparing the pseudorapidity distribution in two different polarization configurations for proton and electron beams. Furthermore, the parity of Pc(4312)P_c(4312) can be discerned by analyzing the decay angle in the Pcp+J/ψP_c \rightarrow p +J/\psi channel. As the multiplicity of PcP_c production in our calculation is large, the EIC can be considered as a future facility for precision measurement of heavy pentaquarks.
