Isovector axial vector form factors of octet–decuplet hyperon transition in QCD

2015 
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 Σ and Λ baryons distribution amplitudes, which are examined up to twist-6 based on conformal symmetry of the massless QCD Lagrangian.
