$B_{c}$ meson decays into $S$ -wave charmonium plus light meson pairs in the perturbative QCD approach

Jia-Ying Wang, Jing Jiang, Yu-Jie Liu +4

In this work, we explore the $P$ -wave resonance contributions to the three-body charmonium decays of $B_{c} \to Ψ (V \to) P_{1} P_{2}$ using the perturbative QCD formalism at leading order,…

Improved global determination of two-meson distribution amplitudes from multi-body $B$ decays

Da-Cheng Yan, Hsiang-nan Li, Zhou Rui +2

We improve the perturbative QCD (PQCD) formalism for multi-body charmless hadronic $B$ meson decays, such as $B \to V P_{3} \to P_{1} P_{2} P_{3}$ , by resolving the possible discrepancy in para…

$C P$ -violating observables of four-body $B_{(s)} \to (π π) (K K ˉ)$ decays in perturbative QCD

Da-Cheng Yan, Yan Yan, Zhou Rui

In this work, we investigate six helicity amplitudes of the four-body $B_{(s)} \to (π π) (K K ˉ)$ decays in the perturbative QCD (PQCD) approach. The $π π$ invariant mass spectrum…

Study of four-body decays $B_{(s)} \to (π π) (π π)$ in the perturbative QCD approach

Da-Cheng Yan, Zhou Rui, Yan Yan +1

In this work, we make a systematical study on the four-body $B_{(s)} \to (π π) (π π)$ decays in the perturbative QCD approach, where the $π π$ invariant mass spectra are dominated by t…
