Description
Gluon exchange currents can explain the decrease of the ratio μpGEp/GMp for four-momentum transfer beyond Q2∼1 GeV2. The SU(6) breaking induced by gluonic currents predicts furthermore that the ratio of neutron to proton magnetic form factors μpGMn/μnGMp falls with increasing Q2. We find that the experimental data are consistent with our expectations of an almost linear decrease of the ratio μpGMn/μnGMp with increasing Q2
