Abstract
We derive an expression for the transition form factor only depending the twist-3 distribution amplitudes by choosing an adequate chiral current correlator in the light-cone QCD sum rules. Our result show that the contribution from the twist-3 distribution amplitudes to the give a constraint on the twist-3 light-cone distribution amplitude.
