Non-perturbaitve effects for the isoscalar light vector $ω$ -meson in charmed meson semileptonic decays

Yin-Long Yang, Fang-Ping Peng, Yan-Ting Yang +2

Motivated by the renewed attention from the recent BESIII experiment on the semileptonic decay $D \to V ℓ ν_{ℓ}$ , we investigate semileptonic decay $D^{+} \to ω ℓ^{+} ν_{ℓ}$ wit…

Searching the possibility of $a_{0} (1450)$ scalar state being a diquark structure via charmed meson semileptonic decays

Ya-Lin Song, Yin-Long Yang, Ye Cao +2

The internal structure of light scalar state $a_{0} (1450)$ has not been definitively determined, it may consist of multiple possible states. Among them, it has the possibility of bei…

Light-cone sum rules analysis of the semi-leptonic $D_{s}^{+} \to f_{0} (980) (\to π^{+} π^{-}) e^{+} ν_{e}$ decay incorporating $f_{0} (980)$ mixing state twist-2 distribution amplitudes

Dan-Dan Hu, Xing-Gang Wu, Hai-Jiang Tian +2

The isospin-singlet scalar meson $f_{0} (980)$ is hypothesized to consist of two energy eigenstates, forming a mixture of $\frac{1}{2} (u ˉ u + d ˉ d)$ and $s ˉ s$ . Bui…

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-…

Exploring the exclusive decay $B^{+} \to ω ℓ^{+} ν$ with light-cone sum rules

Yin-Long Yang, Ya-Lin Song, Fang-Ping Peng +3

In this paper, we calculate the Cabibbo-Kobayashi-Maskawa matrix element $∣ V_{u b} ∣$ by the semileptonic decay $B^{+} \to ω ℓ^{+} ν$ . For the transition form factors (TFFs) $A_{1} (q^{2})$ ,…

$η_{c}$ leading-twist distribution amplitude and the $B_{c} \to η_{c} ℓ ν ˉ_{ℓ}$ semileptonic decays using QCD Sum Rules

Long Zeng, Xing-Gang Wu, Dan-Dan Hu +3

In this paper, we investigate the semileptonic decays $B_{c} \to η_{c} ℓ ν ˉ_{ℓ}$ using the quantum chromodynamics(QCD) sum rules within the framework of Standard Model (SM). We fu…
