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

Understand

Due to the very short life time of the $\Delta$ 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 moments of $\Delta^{++}$ and $\Delta^{+}$ systems there are some experimental data, the theoretical, phenomenological and lattice calculations could play crucial role.
• In present work, the magnetic dipole ($\mu_{\Delta}$) , electric quadrupole ($Q_{\Delta}$) and magnetic octupole ($O_{\Delta}$) moments of these baryons are computed within the light cone QCD sum rules.
• The results are compared with the predictions of the other phenomenological approaches, lattice QCD and existing experimental data.
