Charmed baryon decays at BESIII
Abstract
BESIII has accumulated 6.4~fb−1 of e+e- collision data at center-of-mass energies from 4.60 to 4.95~GeV, corresponding to the world's largest sample of Λc+Λ̅c- pairs. This proceeding summarizes recent BESIII results on charmed baryon decays, including the first observation of the transverse polarization of the Λc+ in e+e-→Λc+Λ̅c-, a precision measurement of the inclusive decay Λc+→ΛX, the first observations of Λc+→ ne+νe and Λc+→ nπ+η with deep-learning techniques, the first observation of Λc+→ pK-e+νe together with evidence for Λc+→Σ±π∓ e+νe, and partial wave analyses of Λc+→Λπ+η.

This proceeding summarizes recent BESIII results on charmed baryon decays, including the first observation of the transverse polarization of the Λ_c^+ in e^+e^-→Λ_c^+Λ̅_c^-, a precision measurement of the inclusive decay Λ_c^+→ΛX, the first observations of Λ_c^+→ ne^+ν_e and Λ_c^+→ nπ^+η with deep-learning techniques, the first observation of Λ_c^+→ pK^-e^+ν_e together with evidence for Λ_c^+→Σ^±π^∓ e^+ν_e, and partial wave analyses of Λ_c^+→Λπ^+η.
