$a_{0} (1450)$ -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…

Probing the equivalence of chiral LCSRs in $D \to I ¨ e I^½_{e}$ decays and extraction of $∣ V_{c d} ∣$

Xiu-Fen Wang, Hai-Jiang Tian, Yin-Long Yang +2

In the paper, we have carried out research on the $D \to I ¨ $ decay process. We employ two different currents to study the $D \to I ¨ $ transition form factors (TFFs) by using the light-c…

Light-cone sum rules analysis of the semi-leptonic $D_{s}^{+} \to f_{0} (980) (\to I ¨ ^{+} I ¨ ^{-}) e^{+} I^½_{e}$ 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…

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…

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…
