Characterize the properties of $D_{s}^{+}$ -meson decay constant and leptonic decays by using QCD sum rules within background field theory framework

Jian-Qi Chen, Ya-Xiong Wang, Hai-Bing Fu

The leptonic decays of the $D_{s}^{+}$ -meson have received considerable attention in recent years. In this work, we perform a precise calculation of the decay constant $f_{D_{s}^{+}}$ usin…

Vector mesons leading-twist longitudinal distribution amplitudes and related semi-leptonic decays within QCD sum rules

Wan-Bing Luo, Ru-Meng Pan, Ya-Xiong Wang +1

In this work, we focus on the light vector meson leading-twist longitudinal distribution amplitudes (DAs) $ϕ_{2; V}^{∥} (x, μ)$ with $V = ρ, K^{*}, ϕ$ . A new scheme of QCD sum…
