Branching fractions and polarizations of D→Vℓν_{ℓ} within QCD light-cone sum rule
In this paper, we make a detailed study of the D→V helicity form factors (HFFs) within the framework of the QCD light-cone sum rule (LCSR) up to twist-4 accuracy. After extrapolating the LCSR predictions of HFFs to the whole physical q^{2} region, we get the longitudinal, transverse, and total |V_{c...
