| 英文摘要 | By considering the nonperturbative QCD effect via quark and gluon condensates, the Confinement terms in effective q-q potential can automaticallY be given. A potential in the form of (-2alpha(s)/3r) + SIGMA(n-0)infinity a2n+1r2n+1 + (Yukawa-type terms) where positive and negative signs appear alternatively in a2n+1's is proposed. To testify the validity range of QCD sum rules, the experimental baryon spectrum is fitted and the values of a2n+1's as well as their signs are obtained. It is found that in the baryon spectrum calculation, the terms of r3 and r5 are important and higher terms beyond r5 can be neglected. Comparing these values with the result calculated from QCD sum rules, some agreements and disagreements are found. |
