    "abstract": "Recently, the LHCb collaboration reported the first observation of $CP$ violation in baryon decays, with a significance of more than $5\\sigma$. This strongly motivates us to investigate the $CP$ violation in more baryon decay processes. In this work, we employ the final-state rescattering mechanism with introducing two model parameters, $\\Lambda_{charm}$ and $\\Lambda_{charmless}$, and calculate two-body non-leptonic baryon decays $\\Lambda^0_b \\rightarrow \\Lambda(1520)\\,\\pi^0/\\kappa(700)/f_0(500, 980)/\\rho^0/K^{*0}/\\phi$ and $\\Xi^-_b \\rightarrow \\Lambda(1520)\\,K^-$. Consequently, we evaluate the corresponding branching ratios, $CP$ asymmetries, and interference effects between different decay amplitudes. Our theoretical predictions for certain decay channels are in good agreement with current experimental measurements, while the remaining processes--particularly the remarkably large $CP$ violation observable revealed by the kinematic analysis are expected to be tested in future experiments.",
