$B_{c} \to J / ψ$ 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…
