Abstract：
In this paper, the D ⁰→π ^－l ⁺ν _ldecay process is studied by applying light-cone QCD sum rules. The form factor of D→π transition is calculated by choosing a correlation function with a chiral current to eliminate the effect caused by the uncertainty of the twist-3 function of the pion. Therefore the calculated result of the form factor is improved, and the branching ratio of the D ⁰→π ^－l ⁺ν _ldecay process is consistent with the new experimental data.
