Electromagnetic transitions among octet and decuplet baryons in QCD
Abstract
The magnetic dipole GM(Q2), electric quadrupole GE(Q2), and Coulomb quadrupole GC(Q2) form factors, describing the spin-3/2 to spin-1/2 electromagnetic transitions, are investigated within the light cone QCD sum rules. The Q2 dependence of these form factors, as well as ratios of electric quadrupole and Coulomb quadrupole form factors to the magnetic dipole form factors are studied. We also compare our results on the magnetic dipole form factor with the prediction of the covariant spectator quark model.
