Nucleon form factors induced by isovector and isoscalar axial-vector currents in QCD

Abstract

Using the most general form of the baryon current, nucleon form factors, induced by isovector and isoscalar axial-vector currents, are studied in the framework of light cone QCD sum rule approach. Comparison of our results on form factors with the existing results and lattice calculations are presented.
