Summary, in English

The transverse momentum spectra and integrated yields of anti-Σ hyperons (Σ¯±) have been measured in pp and p-Pb collisions at sNN=5.02 TeV with the ALICE experiment. Measurements are performed via the newly accessed decay channel Σ¯±→n¯π±. A new method of antineutron reconstruction with the PHOS electromagnetic spectrometer is developed and applied to this analysis. The pT spectra of Σ¯± are measured in the range 0.5
