Abstract
Abstract

We study one possible production mechanism for the hidden-charm pentaquark via a color-octet pair fragmentation in e+e collision. The pentaquark production at B factory energy is dominated by , 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.
