Prospective analysis of CKM element |Vcd| and D+-meson decay constant from leptonic decays D+ → ℓ+ν
The leptonic decay of D+-meson has attracted significant interest due to its unique characteristics. In this paper, we carry out an investigation into the D+-meson leptonic decays D+→ℓ+νℓ with ℓ=(e,μ,τ) by employing the QCD sum rules approach. In which the D+-meson decay constant fD+ is an important...
