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…
