1. P-wave contributions to Bψππ decays in the perturbative QCD approach / Rui, Zhou ; Li, Ya ; Li, Hsiang-nan
We present the differential branching fractions for the Bψππ decays with the charmonia ψ=J/ψ,ψ(2S) in the invariant mass of the P-wave pion pairs in the perturbative QCD approach. [...]

2. Quasi-two-body decays B(s)Pf2(1270)Pππ in the perturbative QCD approach / Li, Ya ; Ma, Ai-Jun ; Rui, Zhou ; Wang, Wen-Fei ; et al
In this work, we calculate the CP-averaged branching ratios and direct CP-violating asymmetries of the quasi-two-body decays B(s)Pf2(1270)Pππ with the two-pion distribution amplitude ΦππD by using the perturbative QCD factorization approach, where P represents a light pseudoscalar meson K, π, η and η.

3. Semileptonic decays of Bc meson to P-wave charmonium states / Rui, Zhou ; Zhang, Jie ; Zhang, Li-li
Inspired by a series of unexpected measurements of semileptonic decays mediated via bc charged current interactions, we explore semileptonic Bc decays to the four lightest P-wave charmonium states, χc0,χc1,χc2,hc, by the recently developed improved perturbative QCD formalism, in which the charm quark mass effect is included both in the Sudakov factor and the hard kernels. [...]

5. S-wave Kπ contributions to the hadronic charmonium B decays in the perturbative QCD approach / Rui, Zhou ; Wang, Wen-Fei

6. Probing the P-wave charmonium decays of Bc meson / Rui, Zhou
Motivated by the large number of Bc meson decay modes observed recently by several detectors at the LHC, we present a detailed analysis of the Bc meson decaying to the P-wave charmonium states and a light pseudoscalar (P) or vector (V) meson within the framework of perturbative QCD factorization.
