Reconsideration of the $B\to K^{\ast }$ Transition Form Factors within the QCD Light-Cone Sum Rules

Wei Cheng, Xing-Gang Wu, Hai-Bing Fu

In this paper, we study the $B\to K^{\ast }$ transition form factors (TFFs) within the QCD light-cone sum rules (LCSR) approach. Two correlators, i.e. the usual one and the right-handed…
