Axial vector transition form factors of $N \rightarrow Δ$ in QCD

The isovector axial vector form factors of $N \rightarrow Δ$ transition are calculated by employing Light-cone QCD sum rules. The analytical results are analysed by 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 Monte Carlo 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.

The axial charge of Δbaryon in QCD

The iso-vector axial-vector form factors of the Δ-Δtransition are calculated in the framework of the Light-cone QCD sum rules method. Also, axial charge of Δbaryon is predicted.

Isovector Axial Vector Form Factors of Octet-Decuplet Hyperon Transition in QCD

We calculate the isovector axial vector form factors of the octet-decuplet hyperon transitions within the framework of the light-cone QCD sum rules (LCSR) to leading in QCD and including higher-twist corrections. In particular, we motivate the most recent version of the $Σ$ baryon distribution amplitudes which are examined up to twist-6 based on conformal symmetry of the massless QCD Lagrangian.

Isovector axial vector and pseudoscalar transition form factors of $Δ$ in QCD

We investigate the isovector axial vector and pseudoscalar form factors of $Δ$ 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.
