dc.descriptionWe derive an expression for the $B\toπ$ 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 $f_{Bπ}^+(q^2)$ give a constraint on the twist-3 light-cone distribution amplitude.
