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…
