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…

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) $A_{1} (q^{2})$ ,…

Footprint in fitting $B \to D$ vector form factor and determination for $D$ -meson leading-twist LCDA

Sheng-Bo Wu, Hai-Jiang Tian, Yin-Long Yang +3

In this paper, we fit the $B \to D$ vector transition form factor (TFF) by using the data measured by \textsl{BABAR} and Belle Collaborations within Monte Carlo (MC) method. Meanwhi…

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

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…
