The ratio $R (D_{s})$ for $B_{s} \to D_{s} ℓ ν_{ℓ}$ by using the QCD light-cone sum rules within the framework of heavy quark effective field theory

Yi Zhang, Tao Zhong, Hai-Bing Fu +3

In the paper, we study the $B_{s} \to D_{s}$ transition form factors by using the light-cone sum rules within the framework of heavy quark effective field theory. We adopt a chiral curr…

The $D_{s}$ -meson leading-twist distribution amplitude within the QCD sum rules and its application to the $B_{s} \to D_{s}$ transition form factor

Yi Zhang, Tao Zhong, Hai-Bing Fu +2

We make a detailed study on the $D_{s}$ meson leading-twist LCDA $ϕ_{2; D_{s}}$ by using the QCD sum rules within the framework of the background field theory. To improve the precision,…

The Ratio $R (D)$ and the $D$ -meson Distribution Amplitude

Tao Zhong, Yi Zhang, Xing-Gang Wu +2

In this paper, we calculate the $B \to D$ transition form factors (TFFs) within the light-cone sum rules (LCSR) and predict the ratio $R (D)$ . More accurate $D$ -meson distr…
