$C P$ 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 $π^{-}$ , $…

Final-state rescattering mechanism in bottom-baryon decays

Zhu-Ding Duan, Jian-Peng Wang, Run-Hui Li +2

The first observation of $C P$ violation in baryon decays was recently reported by the LHCb collaboration in $Λ_{b}^{0} \to p K^{-} π^{+} π^{-}$ with $A_{C P} = (2.45 \pm 0.46 \pm 0.10) %$ , which…

Establishing CP Violation in $b$ -Baryon Decays

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

It is a long-standing puzzle why the {\it CP} violation (CPV) in the baryon system has not yet been definitively established as in the meson one. We demonstrate that individual par…

Branching fractions of $B^{-} \to D^{-} X_{0, 1} (2900)$ and their implications

Yan-Ke Chen, Jia-Jie Han, Qi-Fang Lü +2

The exotic states $X_{0, 1} (2900)$ with the quark flavor of $cs u ˉ d ˉ$ are recently observed in the mass spectrum of $D^{+} K^{-}$ in $B^{-} \to D^{-} D^{+} K^{-}$ by the LHCb collaboration…
