| Abstract: | The coupling vertex of the Pomeron to nucleon is derived from
QCD. A γμ coupling vertex and coupling strength of
β=6.0 GeV-1, 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 IG
JPC=0+ 2++ in nature. |
