Abstract：
We derive and express for the B→π transition form factor only depending on the twist-3 distribution amplitudes by choosing an adequate chiral current correlator in the light-cone QCD sum rules.Our result shows that the contribution from the twist-3 distribution amplitudes to the f+Bπ(q2)gives a constraint on the twist-3 light-cone distribution amplitude.
