Magnetic Dipole, Electric Quadrupole and Magnetic Octupole Moments of the ∆ Baryons in Light Cone QCD Sum Rules

Due to the very short life time of the ∆ baryons, a direct measurement on the electromagnetic moments of these systems is almost impossible in the experiment and can only be done indirectly. Although only for the magnetic dipole moment of ∆++ system there is some experimental data, the theoretical, phenomenological and lattice calculations could play crucial role. In present work, by calculating the electromagnetic form factors of the ∆ baryons at q2 = 0 limit within the light cone QCD sum rules, the magnetic dipole (μ∆) , electric quadrupole (Q∆) and magnetic octupole (O∆) moments of these baryons are computed and compared with the predictions of the other approaches and existing experimental data.
