Exclusive Determination of $∣ V_{c b} ∣$ from Semileptonic Decays $B \to D^{(*)} ℓ ν_{ℓ}$

Xue-Wen Chen, Bo-Yan Cui, Jia-Wei Zhang +2

We present an updated exclusive determination of the CKM matrix element $|V_{cb}|$ from the semileptonic decays $B\to D^{(*)}\ell\barν_{\ell}$. Our analysis combines the latest…

Quasi-two-body decays $B \to P f_{0} (500) \to P π^{+} π^{-}$ in the perturbative QCD approach

Jia-Wei Zhang, Bo-Yan Cui, Xing-Gang Wu +2

In this paper, we study the quasi-two-body decays $B \to P f_{0} (500) \to P π^{+} π^{-}$ [with $P = (π, K, η, η^{'})$ ] within framework of perturbative QCD (PQCD) factorization approach.…

QCD factorization for the $B \to γ ℓ ν_{ℓ}$ decay beyond leading power

Bo-Yan Cui, Yue-Long Shen, Chao Wang +1

The radiative leptonic $B \to γ ℓ ν_{ℓ}$ decay serves as an ideal platform to determine the $B$ -meson inverse moment which is a fundamental nonperturbative parameter for the $B$ …

Contributions of $K_{0}^{} (1430)$ and $K_{0}^{} (1950)$ in the charmed three-body $B$ meson decays

Bo-Yan Cui, Ya-Hui Chen

In this work, we investigate the resonant contributions of $K_{0}^{*} (1430)$ and $K_{0}^{*} (1950)$ in the three-body $B_{(s)} \to D_{(s)} K π$ within the perturbative QCD approach. The form f…

Shedding New Light on $R (D_{(s)}^{()})$ and $∣ V_{c b} ∣$ from Semileptonic $B ˉ_{(s)} \to D_{(s)}^{()} ℓ ν ˉ_{ℓ}$ Decays

Bo-Yan Cui, Yong-Kang Huang, Yu-Ming Wang +1

We compute for the first time the next-to-leading-order QCD corrections to the $B ˉ_{(s)} \to D_{(s)}^{(*)}$ form factors at large hadronic recoil. Both the charm-quark-mass…

Precision calculations of $B_{d, s} \to π, K$ decay form factors in soft-collinear effective theory

Bo-Yan Cui, Yong-Kang Huang, Yue-Long Shen +2

We improve QCD calculations of the $B_{d, s} \to π, K$ form factors at large hadronic recoil by implementing the next-to-leading-logarithmic resummation for the obtained leading-po…

Quasi-two-body decays $B_{(s)} \to P D_{0}^{*} (2400) \to P D π$ in the perturbative QCD approach

Bo-Yan Cui, Ying-Ying Fan, Fu-Hu Liu +1

We study the quasi-two-body decays $B \to P D_{0}^{*} (2400) \to P D π$ with $P = (π, K, η, η^{'})$ in the perturbative QCD factorization approach. The predicted branching fractio…
