文摘The coupling vertex of the Pomeron to nucleon is derived from QCD. A coupling vertex and coupling strength of , which has been used commonly as a free parameter in literature, are obtained. The result leads a support to the belief that the Pomeron could be a tensor glueball ξ(2230) with quantum numbers of in nature.
