Abstract

The form-factors for the transition N(1535)N N^*(1535)\to N induced by isovector and isoscalar axial currents within the framework of light-cone QCD sum rules by using the most general form of the interpolating current are calculated. In numerical calculations, we use two sets of values of input parameters. It is observed that the Q2 Q^2 dependence of the form-factor GA G_A can be described by the dipole form. Moreover, the form-factors GP(S) G_P^{(S)} are found to be highly sensitive to the variations in the auxiliary parameter β \beta .
