| 英文摘要 | The scaling behaviors of the nucleon resonance transition amplitudes from perturbative QCD (PQCD) are utilized to parametrize the amplitudes of the first negative-parity nucleon resonance S-11(1535). Our analysis indicates that the constraints of the transition amplitude for the S-11 resonance at the limit Q(2) --> infinity by QCD sum rule calculations are not applicable at a moderate Q(2) range of 2.5 similar to 4 GeV2 compared with the present available data if the contribution of S-11 is dominant in the Q(2) limit. |
