Abstract

The transverse momentum distributions of the strange and double-strange hyperon resonances (Σ (1385)±, Ξ (1530)0) produced in p–Pb collisions at sNN=5.02 TeV were measured in the rapidity range - 0.5 < yCMS< 0 for event classes corresponding to different charged-particle multiplicity densities, ⟨ dNch/dηlab⟩. The mean transverse momentum values are presented as a function of ⟨ dNch/dηlab⟩ , as well as a function of the particle masses and compared with previous results on hyperon production. The integrated yield ratios of excited to ground-state hyperons are constant as a function of ⟨ dNch/dηlab⟩. The equivalent ratios to pions exhibit an increase with ⟨ dNch/dηlab⟩ , depending on their strangeness content.
