摘要：

We report on the first lattice calculation of light-cone distribution amplitudes of the N*(d1535) resonance, which are used to calculate the transition form factors at large momentum transfers using light-cone sum rules. In the region Q(2) > 2 GeV(2), where the light-cone expansion is expected to converge, the results appear to be in good agreement with the experimental data.
