| contents | The observed matter-antimatter asymmetry in the universe is a serious challenge to our understanding of nature. Baryon/lepton number violation (BNV/LNV) decays have been searched for in many experiments to understand this large-scale observed fact. We present the recent results from the BESIII experiment, including a search for BNV through $Λ-\barΛ$ oscillation in the decays $J/ψ\to pK^-\barΛ$ and $J/ψ\toΛ\barΛ$. We also present searches for LNV in $D_s^+\to h^+h^0e^+e^-$ and $ω/ϕ\toπ^+π^-e^+e^-$ decays, alongside probes into processes violating both baryon and lepton numbers simultaneously, such as $Ξ^0\to K^+e^-/K^-e^+$. |
