$B_{c} \to J / ψ$ 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,…
