$η$ - $η^{'}$ mixing and its application in the $B^{+} / D^{+} / D_{s}^{+} \to η^{(')} ℓ^{+} ν_{ℓ}$ 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 $η - η^{'}$ mixing scheme and formulate the tetramixing $η - η^{'} - G - η_{c}$ to study the mixin…

$η_{c}$ 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…

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

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

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