摘要：

The form factors, as well as the helicity amplitudes for the gamma*Nu -> Nu(1535) transition, are calculated in the framework of the QCD light-cone sum rules. The contamination coming from diagonal transition is eliminated by considering combinations of the sum rules corresponding to different Lorentz structures. A similar procedure is applied for the determination of the residue and mass of the negative-parity baryon. A comparison of our predictions on the helicity amplitudes with the existing theoretical and experimental results is also presented.
