Form factor for B→Dlν˜ in the light-cone sum rules with chiral current correlator

Within the framework of QCD light-cone sum rules (LCSR), we calculate the form factor for B→Dlν˜ transitions with chiral current correlator. The resulting form factor depends on the distribution amplitude (DA) of the D-meson. We try to use three kinds of DA models of the D-meson. In the velocity transfer region 1.14
