$B_{(s)} \to S (a_{0} (1450), K_{0}^{*} (1430), f_{0} (1500))$ helicity form factors within QCD light-cone sum rules

Yi Zhang, Wei Cheng, Jia-Wei Zhang +3

In this paper, we investigate the helicity form factors (HFFs) of the $B_{(s)}$ -meson decay into a scalar meson with a mass larger than 1~GeV, {\it i.e.,} $B \to a_{0} (1450)$ , $B_{(s…

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…

$B_{c} \to J / ψ$ helicity form factors and the $B_{c}^{+} \to J / ψ + (P, V, ℓ^{+} ν_{ℓ})$ decays

Wei Cheng, Yi Zhang, Long Zeng +2

In this paper, we calculate the $B_{c} \to J / ψ$ helicity form factors (HFFs) up to twist-4 accuracy by using the light-cone sum rules (LCSR) approach. After extrapolating those HFFs t…

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…

Uncertainties of the $B \to D$ transition form factor from the $D$ -Meson Leading-Twist Distribution Amplitude

Yi Zhang, Tao Zhong, Xing-Gang Wu +3

The $B \to D$ transition form factor (TFF) $f_{+}^{B \to D} (q^{2})$ is determined mainly by the $D$ -meson leading-twist distribution amplitude (DA) , $ϕ_{2; D}$ , if the proper chiral curr…
