Radiative generation of chiral vector operators in $b \to s ν ν ˉ$ transition

Xin-Shuai Yan, Wen-Feng Liu, Qin Chang +1

The recent Belle II evidence for $B^{+} \to K^{+} ν ν ˉ$ , combined with a suppressed branching fraction ratio $R \equiv \mathcal{B}(B^0 \to K^{*0} ν\barν) / \mathcal{B}(B^+ \to K^+ ν\…

Revisiting the $B$ -physics anomalies in $R$ -parity violating MSSM

Quan-Yi Hu, Ya-Dong Yang, Min-Di Zheng

In recent years, several deviations from the Standard Model predictions in semileptonic decays of $B$ -meson might suggest the existence of new physics which would break the lepton-…

Semi-inclusive Decay $B \to ϕ X_{s}$ : Rate and Momentum Spectrum of $ϕ$

Gad Eilam, Yadong Yang

We study the rate and $ϕ$ momentum distribution in semi-inclusive decays $B \to ϕ X_{s}$ induced by the quark level processes $b \to ϕ s$ and $b \to ϕ s g$ , in which the gluon is radiated f…

$B \to ϕ π$ and $B^{0} \to ϕϕ$ in the Standard Model and new bounds on R parity violation

Shaouly Bar-Shalom, Gad Eilam, Ya-Dong Yang

We study the pure penguin decays $B \to ϕ π$ and $B^{0} \to ϕϕ$ . Using QCD factorization, we find $B (B^{\pm} \to ϕ π^{\pm}) = 2. 0_{- 0.1}^{+ 0.3} \times 1 0^{- 8}$ . For the pure penguin…

Semileptonic and nonleptonic B decays to three charm quarks: B->J/psi (eta_c) D l nu and J/psi (eta_c) D pi

G. Eilam, M. Ladisa, Y. D. Yang

We evaluate the form factors describing the semileptonic decays $B^{0} ˉ \to J / ψ (η_{c}) D^{+} ℓ^{-} ν ˉ_{ℓ}$ , within the framework of a QCD relativistic potential model. This dec…

Study of Semileptonic Decays $B^{\pm} \to η^{(')} l ν$

C. S. Kim, Ya-Dong Yang

We study semileptonic decays $B^{\pm} \to η^{(')} l ν$ , which are suggested to be used to extract the hadronic form factors of $B$ meson decays to $η (η^{'})$ and the angle…

Study of B0-->J/Psi D() and etac D() in Perturbative QCD

Gad Eilam, Massimo Ladisa, Ya-Dong Yang

Motivated by recent interest in soft $J /Ψ$ production in B decays, we investigate $B^{0} \to J /Ψ D^{(⋆)}$ and $η_{c} D^{(⋆)}$ decays in perturbative QCD. We find that, within…
