摘要We study the nucleon form factors and the nucleon-A(1232) transitions ill a framework of hypercentral constituent quark model. The pion meson cloud effect is taken into account explicitly. Our results show that the pion cloud contributes substantially to the nucleon form factors as well as to the helicity amplitudes of A(1232), and it gives air improved agreement compared to the experimental measurement.
