Iso-vector Form Factors of the Delta and Nucleon in QCD Sum Rules

2012-06-21
Form factors are important non-perturbative properties of hadrons. They give information about the internal structure of the hadrons. In this work, iso-vector axial-vector and iso-vector tensor form factors of the nucleon and the iso-vector axial-vector Delta -> N transition form factor calculations in QCD Sum Rules are presented.

The form factors and the branching ratio of the B --> a(1)lv decay are calculated in framework of QCD sum rules. A comparison of our results on form factors and branching ratio with the results from constituent quark model is presented. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
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.
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.
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.
Tensor form factors of nucleon in QCD
ERKOL, GÜRAY; Özpineci, Altuğ (2011-10-25)
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 ...
