Addressing the lightest $S$ -wave strange $K_{0}^{*} (700) / I^º$ resonance in four-body semileptonic $B ˉ_{s}^{0} \to K^{0} I ¨ ^{+} ℓ^{-} I^ˉ ½_{ℓ}$ decays

Dong Huang, Sheng-Bo Wu, Fang-Ping Peng +2

As the lightest strange scalar resonance, $K_{0}^{*} (700)$ (also called $I^º$ ) has a large width and resides close to the $K I ¨ $ threshold, leading to a longstanding debate about its int…

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…

$I^\cdot$ - $I^\cdot^{'}$ mixing and its application in the $B^{+} / D^{+} / D_{s}^{+} \to I^\cdot^{(')} ℓ^{+} I^½_{ℓ}$ decays

Yu-Jie Zhang, Xing-Gang Wu, Dan-Dan Hu +1

In this paper, we take into account the intrinsic charm and gluonic contents into the $I^\cdot - I^\cdot^{'}$ mixing scheme and formulate the tetramixing $I^\cdot - I^\cdot^{'} - G - I^\cdot_{c}$ to study the…

$I^\cdot_{c}$ leading-twist distribution amplitude and the $B_{c} \to I^\cdot_{c} ℓ I^ˉ ½_{ℓ}$ semileptonic decays using QCD Sum Rules

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

In this paper, we investigate the semileptonic decays $B_{c} \to I^\cdot_{c} ℓ I^ˉ ½_{ℓ}$ using the quantum chromodynamics(QCD) sum rules within the framework of Standard Model (SM). We…

Longitudinal leading-twist distribution amplitude of the $^{1} P_{1}$ -state $b_{1} (1235)$ meson and its implications on $B \to b_{1} (1235) ℓ^{+} I^½_{ℓ}$ decays

Long Zeng, Xing-Gang Wu, Dan-Dan Hu +2

In the paper, we derive the $I^¾$ -moments $⟨ I^¾_{2; b_{1}}^{n; ∥} ⟩$ of the longitudinal leading-twist distribution amplitude $I ¨ _{2; b_{1}}^{∥}$ for $^{1} P_{1}$ -state $b_{1} (1235)$ -…
