### Description

The ALICE Experiment features low material budget and high resolution tracking, which allow for precise measurements of charged particle production. The measurement of the antibaryon-to-baryon ratios ($\overline{\rm{B}}$/B), in particular, probes the baryon transport and degree of baryon stopping in high energy interactions, providing insight into the collision dynamics and the structure of baryons. In this poster I will discuss the measurement of different ($\overline{\rm{B}}$/B) ratios ($\overline{\rm p}/{\rm p}$, $\overline{\Lambda}/{\Lambda}$, ${{\overline{\Xi}}^{+}}/{\Xi^{-}}$, ${{\overline{\Omega}}^{+}}/{\Omega^{-}}$) in Pb-Pb at $\sqrt{s_{\rm NN}} = 2.76$ TeV and p-Pb at $\sqrt{s_{\rm NN}} = 5.02$ TeV as a function of the charged particle multiplicity density, rapidity and transverse momentum. Results from Pb-Pb and p-Pb are presented and compared to models.
