Özet

The magnetic dipole G(M)(Q(2)), electric quadrupole G(E)(Q(2)), and Coulomb quadrupole G(C)(Q(2)) form factors, describing the spin-3/2 to spin-1/2 electromagnetic transitions, are investigated within the light cone QCD sum rules. The Q(2) 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.
