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.

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...
Scalar form factor of the nucleon and nucleon-scalar meson coupling constant in QCD Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2007-02-01) Scalar form factor of the nucleon is calculated in the framework of light-cone QCD sum rules, using the most general form of the baryon current. Using the result on scalar form factor of the nucleon, the nucleon-scalar sigma and a(0) meson coupling constants are estimated. Our results on these couplings are in good agreement with the prediction of the external-field QCD sum rules method.
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 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.
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.
