Özet

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.
