摘　　要：We study one possible production mechanism for the hidden-charm pentaquark via a color-octet cc pair fragmentation in e^(+)e^(-)collision.The pentaquark production at B factory energy is dominated by e^(+)e^(-)→ccg→P_(c)+X,while at Z^(0)pole energy,there are several partonic processes playing significant role.Our results show that it is possible to search for the direct pentaquark production signal at e^(+)e^(-)colliders,which is important to understand the properties of pentaquark.
