Description

Baryonic resonances are highly sensitive observables for understanding the late-stage dynamics and particle production mechanisms in high-energy collisions. Because their lifetimes (≈ 12.6 fm/c for the Λ(1520) and ≈ 21.7 fm/c for the Ξ(1530)0) are of the same order as the lifespan of the hadronic phase, they provide a unique window into re-scattering and regeneration effects. This work presents recent measurements of Λ(1520) and Ξ(1530)0 states collected by the ALICE experiment during LHC Run 3. We highlight the evolution of transverse momentum spectra, integrated yields, and mean transverse momentum across different collision systems, with a special emphasis on light-ion data.
