| Abstract: | 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→ Pc+X, while at Z0 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. |
