$a_{0} (1450)$ -state twist-2 light-cone distribution amplitude moments within QCD sum rules and its implication in $B ˉ^{0} \to a_{0} (1450)^{+} ℓ^{-} I^ˉ ½_{ℓ}$ decays

Ya-Lin Song, Yin-Long Yang, Yan-Ting Yang +4

Based on longstanding puzzle for the structure of light scalar meson, it is meaningful to make a deep research for its property in different decay processes especially in the botto…

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 $B^{+} \to I ¨ ℓ^{+} I^½$ 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 $B^{+} \to I ¨ ℓ^{+} I^½$ . For the transition form factors (TFFs) $A_{1} (q^{2})$ …
