| Abstract | These proceedings present measurements of the $\Xi^{-}$, $\overline{\Xi}^{+}$, $\Omega^{-}$, $\overline{\Omega}^{+}$ masses and mass differences between particle and anti-particle, in pp collisions at $\sqrt{s} = 13$ TeV collected by the ALICE Collaboration during the LHC Run 2. Relying on a data sample much larger than those used in past experiments, the results improve significantly the values obtained from previous measurements and thus offer the opportunity to test directly the CPT symmetry to an unprecedented level of precision in the multi-strange baryon sector. |
