We present the first lattice QCD determination of the Λ → N vector and axial-vector form factors, which are essential inputs for studying the semileptonic decay $\Lambda\rightarrow p \ell \overline{\nu}_\ell$. This channel provides a clean, theoretically controlled avenue for extracting the CKM matrix element |$V_{us}$| from the baryon sector. Our analysis uses a gauge ensemble with physical...
