$B\to K^{\ast }$ Transition Form Factors and the Semi-leptonic Decay $B\to K^{\ast }{\mu }^{+}{\mu }^{-}$

Hai-Bing Fu, Xing-Gang Wu, Yang Ma +2

We present a detailed calculation on the $B\to K^{\ast }$ transition form factors (TFFs), $A_{0,1,2}$, $V$ and $T_{1,2,3}$, within the QCD light-cone sum rules (LCSR). To suppress the co…
