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 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.
Electromagnetic form factors of the rho meson in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2004-11-01) We investigate the electromagnetic form factors of the rho meson in light cone QCD sum rules. We find that the ratio of the magnetic and charge form factors is larger than 2 at all values of Q(2), (Q(2)greater than or equal to0.5 GeV2). The values of the individual form factors at fixed values of Q(2) predicted by the light cone QCD sum rules are quite different compared to the results of other approaches. These results can be checked in the future, when more precise data on rho meson form factors is availa...
Strong coupling constants of decuplet baryons with vector mesons Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2010-11-10) We provide a comprehensive study of strong coupling constants of decuplet baryons with light nonet vector mesons in the framework of light cone QCD sum rules. Using the symmetry arguments, we argue that all coupling constants entering the calculations can be expressed in terms of only one invariant function even if the SU(3)(f) symmetry breaking effects are taken into account. We estimate the order of SU(3)(f) symmetry violations, which are automatically considered by the employed approach.
Strong coupling constants of light pseudoscalar mesons with heavy baryons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-01-31) We calculate the strong coupling constants of light pseudoscalar mesons with heavy baryons within the light cone QCD sum rules method. It is shown that sextet-sextet, sextet-antitriplet and antitriplet-antitriplet transitions are described by one universal invariant function for each class. A comparison of our results on the coupling constants with the predictions existing in literature is also presented.
Radiative decays of decuplet to octet baryons in light cone QCD Alıyev, Tahmasıb; Özpineci, Altuğ (Elsevier BV, 2006-01-02) The radiative decays of decuplet to octet baryons are analyzed within the light cone QCD sum rules framework. The electromagnetic transition form factors for these decays are calculated at q(2) = 0 up to twist-4 accuracy for photon wave functions and including first order strange quark mass corrections. A comparison of our results with predictions of lattice theory and existing experimental data is presented. (c) 2005 Published by Elsevier B.V.
