Final-state rescattering in $B ˉ_{(s)}^{0} \to Λ_{c}^{+} Λ ˉ_{c}^{-}$ decays

Zhu-Ding Duan, Xiao Huang, Dong-Hao Li +3

The LHCb Collaboration has recently reported the first observation of the decay $B ˉ_{s}^{0} \to Λ_{c}^{+} Λ ˉ_{c}^{-}$ , along with measurements of the branching fractions for both $\bar B^…

Probing direct $C P$ violation in $Λ_{b}^{0} \to P_{c}^{+} h^{-}$ $(h = π, K)$ with final-state rescattering

Zhu-Ding Duan, Tian-Liang Feng, Run-Hui Li +3

The LHCb Collaboration recently reported a measurement of the difference in direct CP asymmetries for the decays $Λ_{b}^{0} \to J / ψ p h^{-}$ (with $h = K, π$ ), offering new experime…

$C P$ 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…

Final-state rescattering mechanism of charmed baryon decays

Cai-Ping Jia, Hua-Yu Jiang, Jian-Peng Wang +1

The dynamical studies on the non-leptonic weak decays of charmed baryons are always challenging, due to the large non-perturbative contributions at the charm scale. In this work, w…

CP Violation of Baryon Decays with $N π$ Scatterings

Jian-Peng Wang, Fu-Sheng Yu

There is a long-standing puzzle that the CP violation (CPV) in the baryon systems has never been well established in experiments, while the CPV of mesons have been observed by deca…

Probing hyperon electric dipole moments with a full angular analysis

Jinlin Fu, Hai-Bo Li, Jian-Peng Wang +2

The electric dipole moment (EDM) of elementary particles, arising from flavor-diagonal $C P$ violation, serves as a powerful probe for new physics beyond the Standard Model and hold…

Complementary $C P$ violation induced by $T$ -odd and $T$ -even correlations

Jian-Peng Wang, Qin Qin, Fu-Sheng Yu

In this letter, we propose a novel approach to concurrently measure the complementary $C P$ violation observables induced by $T$ -odd correlations and their corresponding $T$ -even co…

Probing hyperon CP violation from charmed baryon decays

Jian-Peng Wang, Fu-Sheng Yu

CP violation (CPV) in the baryon sectors has not yet been established experimentally. In this work, we propose to search for the hyperon CPV through the Cabibbo-favored charm-baryo…

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…
