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) $I ¨ _{2; V}^{∥} (x, I^¼)$ with $V = I ¨ , K^{*}, I ¨ $ . In order to obtain t…

Status of the $D_{s}^{+} \to I ¨ ℓ^{+} I^½_{ℓ}$ decay with a chiral-odd $I ¨ $ -meson light-cone distribution amplitude

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

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

Probing $∣ V_{cs} ∣$ and lepton flavor universality through $D \to K_{0}^{*} (1430) ℓ I^½_{ℓ}$ decay

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

In this paper, we calculate the semileptonic decays $D \to K_{0}^{*} (1430) ℓ I^½_{ℓ}$ with $ℓ = (e, I^¼)$ induced by $c \to s ℓ I^½_{ℓ}$ transition. For the key component, $D\to…

The rare decay $B^{+} \to K^{+} ℓ^{+} ℓ^{-} (I^½ I^ˉ ½)$ under the QCD sum rules approach

Hai-Jiang Tian, Hai-Bing Fu, Tao Zhong +2

In the paper, we conduct a detailed investigation of the rare decay processes of charged meson, specifically $B^{+} \to K^{+} ℓ^{+} ℓ^{-}$ with $ℓ = (e, I^¼, I ¨ )$ and $B^+ \to K^+Î½\barÎ…

Prospective analysis of CKM element $∣ V_{c d} ∣$ and $D^{+}$ -meson decay constant from leptonic decays $D^{+} \to ℓ^{+} I^½$

Ya-Xiong Wang, Hai-Jiang Tian, Yin-Long Yang +2

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 d…
