Form Factor for $B\to Dl\tilde{\nu }$ in Light-Cone Sum Rules With Chiral Current Correlator

Fen Zuo, Zuo-Hong Li, Tao Huang

Within the framework of QCD light-cone sum rules (LCSR), we calculate the form factor for $B\to Dl\tilde{\nu }$ transitions with chiral current correlator. The resulting form factor d…
