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…
