We calculate the magnetic moments of decuplet baryons containing strange quarks within the framework of light cone QCD sum rules taking into account the SU(3) flavor symmetry breaking effects. It is obtained that magnetic moments of the neutral Sigma(*0) and Xi(*0) baryons are mainly determined by the SU(3) breaking terms. A comparison of our results on the magnetic moments of the decuplet baryons with the predictions of other approaches is presented.

Magnetic moments of heavy Xi Q baryons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ (American Physical Society (APS), 2008-06-01) The magnetic moments of heavy Xi(Q) baryons containing a single charm or bottom quark are calculated in the framework of the light cone QCD sum rules method. A comparison of our results with the predictions of other approaches, such as relativistic and nonrelativistic quark models, the hypercentral model, chiral perturbation theory, and soliton and skyrmion models, is presented.
Magnetic and quadrupole moments of light spin-1 mesons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2009-08-03) The magnetic and quadrupole moments of the light-vector and axial-vector mesons are calculated in the light cone QCD sum rules. Our results for the static properties of these mesons are compared with the predictions of lattice QCD as well as other approaches existing in the literature. (C) 2009 Published by Elsevier B.V.
Electric quadrupole and magnetic octupole moments of the light decuplet baryons within light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (2009-11-02) The electric quadrupole and magnetic octupole moments of the light decuplet baryons are calculated in the framework of the light cone QCD sum rules. The obtained non-vanishing values for the electric quadrupole and magnetic octupole moments of these baryons show nonspherical charge distribution. The sign of electric quadrupole moment is positive for Omega(-). Xi*(-), Sigma*(-) and negative for Sigma*(+), which correspond to the prolate and oblate charge distributions, respectively. A comparison of the obtai...
Magnetic dipole moments of the negative parity J(PC)=2(--) mesons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (2018-04-18) Magnetic dipole moments of the negative parity light and heavy tensor mesons are calculated within the light cone QCD sum rules method. The results are compared with the positive parity counterparts of the corresponding tensor mesons. The results of the analysis show that the magnetic dipole moments of the negative parity light mesons are smaller compared to those of the positive parity mesons. Contrary to the light meson case, magnetic dipole moments of the negative parity heavy mesons are larger than the ...
Magnetic moment of the X-Q state with J(PC)=1(++/-) in light cone QCD sumrules Agamaliev, A. K.; Alıyev, Tahmasıb; Savcı, Mustafa (2017-02-21) The magnetic moments of the recently observed resonance X-b(5568) by D0 Collaboration and its partner with charm quark are calculated in the framework of the light cone QCD sum rules, by assuming that these resonances are represented as tetraquark states with quantum numbers J(PC) = 1(vertical bar +/-). The magnetic moment can play a critical role in the determination of the quantum numbers, as well as give useful information about the inner structure of these mesons.
