We compute the diagonal isovector axial-vector as well as induced pseudoscalar form factors of nucleon, Sigma, and Xi baryons by employing the light-cone QCD sum rules to leading order in QCD and including distribution amplitudes up to twist 6. Extrapolating our sum-rules results to low-momentum transfers, we make a comparison with experimental and lattice-QCD results where we can achieve a nice qualitative and quantitative agreement.

Isovector axial vector and pseudoscalar transition form factors of Delta in QCD KÜÇÜKARSLAN, AYŞE; Ozdem, U.; Özpineci, Altuğ (2014-09-03) We investigate the isovector axial vector and pseudoscalar form factors of Delta baryon by employing light-cone QCD sum rules. Numerical calculations show that the form factors can be well fitted by the exponential form. We make a comparison with the predictions of lattice QCD, chiral perturbation theory and quark model.
Isovector axial vector form factors of octet-decuplet hyperon transition in QCD KÜÇÜKARSLAN, AYŞE; Ozdem, U.; Özpineci, Altuğ (2015-01-01) We calculate the isovector axial vector form factors of the octet-decuplet hyperon transitions within the framework of the light-cone QCD sum rules to leading in QCD and including higher-twist corrections. In particular, we motivate the most recent version of the Sigma and Lambda baryons distribution amplitudes, which are examined up to twist-6 based on conformal symmetry of the massless QCD Lagrangian.
Tensor form factors of the octet hyperons in QCD Küçükarslan, Ayşe; Özdem, Ulaş; Özpineci, Altuğ (American Physical Society (APS), 2016-11-11) Light-cone QCD sum rules to leading order in QCD are used to investigate the tensor form factors of the Sigma-Sigma,Xi-Xi, and Sigma-Lambda transitions in the range 1 GeV2 <= Q(2) <= 10 GeV2. The DAs of Sigma,Xi, and. baryon have been calculated without higher-order terms. Then, studies including higher-order corrections have been done for the Sigma and. baryon Lambda The resulting form factors are obtained using these two DAs. We make a comparison with the predictions of the chiral quark soliton model.
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...
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.
