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 available.

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.
Octet negative parity to octet positive parity electromagnetic transitions in light cone QCD
Alıyev, Tahmasıb; Savcı, Mustafa (IOP Publishing, 2014-07-01)
Light cone QCD sum rules for the electromagnetic transition form factors among positive and negative parity octet baryons are derived. The unwanted contributions of the diagonal transitions among positive parity octet baryons are eliminated by combining the sum rules derived from different Lorentz structures. The Q(2) dependence for the transversal and longitudinal helicity amplitudes are studied.
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.
Electromagnetic form factors of octet baryons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2013-06-10)
The electromagnetic form factors of octet baryons are estimated within light cone QCD sum rules method, using the most general form of the interpolating current for baryons. A comparison of our predictions on the magnetic dipole and electric form factors with the results of other approaches is performed.
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.
