We study the nucleon electromagnetic form factors in a quark–gluon core model framework, which can be viewed as an extension of the Isgur–Karl model of baryons. Using this picture we derive nucleon electromagnetic dipole form factors at low Q 2 and the deviation from the dipole form at high Q 2, that are consistent with the existing experimental data.
