| contents | We present an overview of a novel approach to the QCD Light-Cone Sum Rule method, employing $B$-meson Light-Cone Distribution Amplitudes. This method circumvents the semi-global quark-hadron duality (QHD) approximation, which can introduce an unknown and potentially significant systematic error in form factor predictions. Instead, our approach is more dependent on higher-order contributions in perturbation theory and higher-twist contributions. Unlike the systematic errors from semi-global QHD, truncation errors can be evaluated and systematically improved, allowing for robust form factor predictions. |
