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.

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 dipole moment of the light tensor mesons in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (IOP Publishing, 2010-07-01) The magnetic dipole moments of the light tensor mesons f(2), a(2) and the strange K-2*(0)(1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral f(2) and a(2) tensor mesons, while it has a small nonzero value for the neutral strange K-2*(0)(1430) tensor meson.
Magnetic Moments of 70-Plet Baryons in Quark Model and QCD Sum Rules Alıyev, Tahmasıb (2015-01-01) Magnetic moments of the positive parity 70-plet baryons are estimated in the framework of the nonrelativistic quark model and QCD sum rules method. It is found that the magnetic moments of the 70-plet baryons can be expressed in terms of the F and D couplings and exhibit unitary symmetry. The QCD sum rules for the magnetic moments of the 70-plet octet baryons are formulated. A comparison of our results on magnetic moments of 56-plet and 70-plet baryons predicted from QCD sum rules 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 moments of decuplet baryons in light cone QCD Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-09-01) 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.
