$B_{c}$ 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,…

$C P$ violation in two-body hadronic $Λ_{b}$ decays in the PQCD approach

Jia-Jie Han, Ji-Xin Yu, Ya Li +4

We systematically investigate the $C P$ -averaged branching ratios and $C P$ violations (CPVs) for the two-body hadronic decays $Λ_{b} \to p h$ , where $h$ runs through the mesons $π^{-}$ , $…

Study of $B_{c} \to χ_{c J} (P, V)$ decays in the improved perturbative QCD formalism

Xin Liu, Hsiang-nan Li, Zhen-Jun Xiao

Motivated by the recent LHCb measurements of the ratios between the branching ratios (BRs), $R_{χ_{c 2} / J / ψ} \equiv BR (B_{c}^{+} \to χ_{c 2} π^{+}) / BR (B_{c}^{+} \to J / ψ π^{+})$ and $R…
