| contents | This work presents the first detailed numerical predictions of CP violation in antitriplet charmed baryon decays. Adopting the flavor $SU(3)_F$ symmetry and the final state re-scattering framework, we relate the CKM-suppressed amplitudes to the leading ones, which are proportional to $λ_b$ and $λ_d$, respectively, with $λ_q = V_{uq}V^*_{cq}$. Larger-than-expected CP violations are found, reaching the order of $10^{-3}$, similar in magnitude to those in $D^0 \to π^+π^- ,K^+K^-$. This opens a promising avenue for observing CP violation in charmed baryon decays and testing the Standard Model. |
