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…

Status of the $D_{s}^{+} \to ϕ ℓ^{+} ν_{ℓ}$ decay with a chiral-odd $ϕ$ -meson light-cone distribution amplitude

Ya-Xiong Wang, Dan-Dan Hu, Wan-Bing Luo +2

The twist-2 distribution amplitude of the $ϕ$ -meson has attracted considerable interest due to its unique properties. In this work, we construct the transverse leading-twist light-…

Scrutinizing $B^{0}$ -meson flavor changing neutral current decay into scalar $K_{0}^{*} (1430)$ meson with $b \to s ℓ^{+} ℓ^{-} (ν ν ˉ)$ transition

Yin-Long Yang, Ya-Xiong Wang, Hai-Bing Fu +2

In this paper, we investigate the rare decay $B^{0} \to K_{0}^{*} (1430) ℓ^{+} ℓ^{-}$ with $ℓ = (e, μ, τ)$ and $B^{0} \to K_{0}^{*} (1430) ν ν ˉ$ induced by the flavor changing neutral current tran…

Probing $∣ V_{cs} ∣$ and lepton flavor universality through $D \to K_{0}^{*} (1430) ℓ ν_{ℓ}$ decay

Yin-Long Yang, Hai-Jiang Tian, Ya-Xiong Wang +4

In this paper, we calculate the semileptonic decays $D \to K_{0}^{*} (1430) ℓ ν_{ℓ}$ with $ℓ = (e, μ)$ induced by $c \to s ℓ ν_{ℓ}$ transition. For the key component, $D\to K_0…
