Tomography of high-twist proton structure through $e p$ elastic scattering

Ji-Xin Yu, Shan Cheng, Jia-Jie Han +2

We present the first high-twist study of the proton form factors $F_{1, 2} (Q^{2})$ in $e p$ elastic scattering based on the perturbative QCD $k_{T}$ factorization, $Q^{2}$ being momentum t…

The $Λ_{b} \to Λ$ transition form factors in perturbative QCD approach

Lei Yang, Jia-Jie Han, Qin Chang +1

In this work, we investigate the $Λ_{b} \to Λ$ transition form factors in the perturbative QCD (PQCD) approach, incorporating higher-twist light-cone distribution amplitudes (LCDAs).…

$C P$ 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…

CP violation observables in baryon decays

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

The era of baryon physics is on the horizon with the accumulation of increasing data by collaborations such as LHCb, Belle II, and BESIII. Despite the wealth of data, one of the cr…
