Quasitwobody decays ${B}_{\left(s\right)}\to P{f}_{2}\left(1270\right)\to P\pi \pi $ in the perturbative QCD approach
/ Li, Ya ; Ma, AiJun ; Rui, Zhou ; Wang, WenFei ; et al
In this work, we calculate the $CP$averaged branching ratios and direct $CP$violating asymmetries of the quasitwobody decays ${B}_{\left(s\right)}\to P{f}_{2}\left(1270\right)\to P\pi \pi $ with the twopion distribution amplitude ${\Phi}_{\pi \pi}^{D}$ by using the perturbative QCD factorization approach, where $P$ represents a light pseudoscalar meson $K$, $\pi $, $\eta $ and ${\eta}^{\prime}$.

Semileptonic decays of ${B}_{c}$ meson to $P$wave charmonium states
/ Rui, Zhou ; Zhang, Jie ; Zhang, Lili
Inspired by a series of unexpected measurements of semileptonic decays mediated via $b\to c$ charged current interactions, we explore semileptonic ${B}_{c}$ decays to the four lightest $P$wave charmonium states, ${\chi}_{c0},{\chi}_{c1},{\chi}_{c2},{h}_{c}$, 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.

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