Öğe Axial vector transition form factors of N ? ? in QCD(Elsevier, 2016) Kucukarslan, A.; Ozdem, U.; Ozpineci, A.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 are in good agreement with other results in the literature. (C) 2016 The Author(s). Published by Elsevier B.V.Öğe Isovector axial vector and pseudoscalar transition form factors of ? in QCD(Amer Physical Soc, 2014) Kucukarslan, A.; Ozdem, U.; Ozpineci, A.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.Öğe Isovector axial vector form factors of octet-decuplet hyperon transition in QCD(Iop Publishing Ltd, 2015) Kucukarslan, A.; Ozdem, U.; Ozpineci, A.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.Öğe Tensor form factors of the octet hyperons in QCD(Amer Physical Soc, 2016) Kucukarslan, A.; Ozdem, U.; Ozpineci, A.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.Öğe The axial charge of ? baryon in QCD(INSPIRE, 2015) Ozdem, U.; Kucukarslan, A.; Ozpineci, A.The iso-vector axial-vector form factors of the ? ? ? transition are calculated in the framework of the Light-cone QCD sum rules method. Also, axial charge of ? baryon is predicted. © Workshop on High Energy Physics and Quantum Field Theory, QFTHEP 2015.All right reserved.
