Electroexcitation of the Delta(1232)3/2+ and Delta(1600)3/2+ in a light-front relativistic quark model

Abstract

The magnetic-dipole form factor and the ratios R_EM and R_SM for the gamma* N -> Delta(1232)3/2}+ transition are predicted within light-front relativistic quark model up to photon virtuality Q2=12 GeV2. We also predict the helicity amplitudes of the gamma* N -> Delta(1600)3/2+ transition assuming the Delta(1600)3/2+ is the first radial excitation of the ground state Delta(1232)3/2+.
