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…

Revisiting the production of $J / ψ + η_{c}$ via the $e^{+} e^{-}$ annihilation within the QCD light-cone sum rules

Long Zeng, Hai-Bing Fu, Dan-Dan Hu +3

We make a detailed study on the typical production channel of double charmoniums, $e^{+} e^{-} \to J / ψ + η_{c}$ , at the center-of-mass collision energy $s = 10.58$ GeV. The key componen…

Branching fractions and polarizations of $D \to V (ω, ρ, K^{*}) ℓ ν_{ℓ}$ within QCD LCSR

Hai-Bing Fu, Wei Cheng, Long Zeng +2

In this paper, we make a detailed study about the $D \to V$ helicity form factors (HFFs) within the framework of QCD light-cone sum rule (LCSR) up to twist-4 accuracy. After extrapo…

$D \to P (π, K)$ helicity form factors within light-cone sum rule approach

Hai-Bing Fu, Wei Cheng, Rui-Yu Zhou +1

In this paper, the $D \to P (π, K)$ helicity form factors (HFFs) are studied by applying the QCD light-cone sum rule (LCSR) approach. The calculation accuracy is up to next-to-leadin…

The $D \to ρ$ semileptonic and radiative decays within the light-cone sum rules

Hai-Bing Fu, Long Zeng, Rong Lü +2

The measured branching ratio of the $D$ meson semileptonic decay $D \to ρ e^{+} ν_{e}$ , which is based on the $0.82 f b^{- 1}$ CLEO data taken at the peak of $ψ (3770)$ resonance, di…
