We extract the isovector tensor nucleon form factors, which play an important role in understanding the transverse spin structure of the nucleon when related to the quark helicity-flip generalized parton distributions via their first moments. We employ the light-cone QCD sum rules to leading order in QCD and include distribution amplitudes up to twist 6 in order to calculate the three tensor form factors H(T). E(T) and (H) over bar (T). Our results agree well with those from other approaches in the low and high momentum-transfer regions.

Tensor form factors of B -> K-1 transition from QCD light cone sum rules Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30) The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.
Strong coupling constants of the octet baryons to Kand pi mesons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ (2007-06-20) In this work, the strong coupling constants of the octet baryons to the K and pi mesons are studied within the Light Cone QCD sum rule method. It is well known that in the SU(3)(f) limit, these couplings can be expressed in terms of only 2 constants, so called F and D constants. In this work, the SU(3)(f) symmetry violating effects are also studied and it is shown that all the coupling constants can be expressed in terms of four analytical functions of the quark parameters.
Axial vector transition form factors of N -> Delta in QCD Küçükarslan, Ayşe; Özdem, Ulaş; Özpineci, Altuğ (Elsevier BV, 2016-12) The isovector axial vector form factors of N -> Delta transition are calculated by employing Light-cone QCD sum rules. The analytical results are analyzedby both the conventional method, and also by a Monte Carlo based approach which allows one to scan all of the parameter space. The predictions are also compared with the results in the literature, where available. Although the MonteCarlo analysis predicts large uncertainties in the predicted results, the predictions obtained by the conventional analysis ar...
Magnetic moments of Delta baryons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-10-23) We calculate the magnetic moments of Delta baryons within the framework of QCD sum rules. A comparison of our results on the magnetic moments of the Delta baryons with the predictions of different approaches is presented.
Electromagnetic form factors of electrodisintegration of light nuclei near threshold Yalcin, C; Rekalo, MP; Koru, H (1998-06-01) The general structure of electromagnetic currents for electrodisintegration of nuclei near threshold, e(-) + A --> e(-) + A(1) + A(2) (A, A(1) and A(2) are arbitrary nuclei or hadrons with spins 0, 1/2 and 1), are established. Considering nuclei as elementary particles with the definite values of spin and space parity and using the conservation of hadronic electromagnetic current and P-invariance of hadron electromagnetic interaction, the spin structure of the amplitudes of the processes gamma* + A --> A(1)...
