英文摘要Based on a relativistic quark model approach, the transition properties of the first nucleon resonance Delta(1232), and the coupling constants gpiNN, gDeltapiN are investigated. Two different ways to remove the center of mass motion are considered. The results of the relativistic approaches with and without center of mass correction are compared with those of nonrelativistic constituent quark model. Moreover, pion meson cloud effect on these calculated observables is explicitly addressed. Better results are obtained by taking the pion meson cloud into account.
