Description
Summary:The transverse momentum distributions of the strange and double-strange hyperon resonances (Σ(1385)±Σ(1385)±\Sigma (1385)^{\pm }, Ξ(1530)0Ξ(1530)0\Xi (1530)^{0}) produced in p-Pb collisions at sNN−−−√=5.02sNN=5.02\sqrt{s_{\mathrm{NN}}}= 5.02 TeV were measured in the rapidity range −0.5<yCMS<0−0.5<yCMS<0-0.5< y_\mathrm {CMS}<0 for event classes corresponding to different charged-particle multiplicity densities, ⟨⟨\langle dNchNchN_{\mathrm{ch}}/dηlab⟩ηlab⟩\eta _{\mathrm{lab}}\rangle . The mean transverse momentum values are presented as a function of ⟨⟨\langle dNchNchN_{\mathrm{ch}}/dηlab⟩ηlab⟩\eta _{\mathrm{lab}}\rangle , 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 ⟨⟨\langle dNchNchN_{\mathrm{ch}}/dηlab⟩ηlab⟩\eta _{\mathrm{lab}}\rangle . The equivalent ratios to pions exhibit an increase with ⟨⟨\langle dNchNchN_{\mathrm{ch}}/dηlab⟩ηlab⟩\eta _{\mathrm{lab}}\rangle , depending on their strangeness content.
