Multiplicity dependence of hyperon and hypertriton production in Zr+Zr and Ru+Ru collisions at √sNN = 200 GeV
We present yield measurements on hyperons (Λ, Λ¯ and Ξ¯, Ξ¯+) and hypertriton (3ΛH, 3/ΛH¯) in four different centrality classes of Zr+Zr and Ru+Ru collisions at √sNN = 200 GeV. The yield ratios of Λ/π−, Ξ−/π−, 3ΛH/Λ and S3= (3ΛH/Λ)/(3He/p) are reported as a function of multiplicity, while the ratio...

| Summary: | We present yield measurements on hyperons (Λ, Λ¯ and Ξ¯, Ξ¯+) and hypertriton (3ΛH, 3/ΛH¯) in four different centrality classes of Zr+Zr and Ru+Ru collisions at √sNN = 200 GeV. The yield ratios of Λ/π−, Ξ−/π−, 3ΛH/Λ and S3= (3ΛH/Λ)/(3He/p) are reported as a function of multiplicity, while the ratio of 3ΛH/3He is reported as a function of pT in each centrality. The comparisons between data and models are discussed. These results provide insights on particle production mechanisms in heavy-ion collisions. |
