$B_{c} \to J / ψ$ 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…

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…
