Enhanced strange baryon production in Au+Au collisions compared to p+p at $\sqrt{s_{NN}}$ = 200 GeV
We report on the observed differences in production rates of strange and multi-strange baryons in Au+Au collisions at sqrts = 200 GeV compared to p+p interactions at the same energy. The yields in Au+Au collisions, when scaled by the number of participants, are larger than those measured in the p+p...

| description | We report on the observed differences in production rates of strange and multi-strange baryons in Au+Au collisions at sqrts = 200 GeV compared to p+p interactions at the same energy. The yields in Au+Au collisions, when scaled by the number of participants, are larger than those measured in the p+p data. The magnitudes of the differences grow with the strangeness of the baryon and with increasing centrality. The enhancements of the Au+Au yields are close to those measured in sqrts = 17.3 GeV collisions. Further, when the binary scaled p+p pT spectra are compared to those of Au+Au the heavy-ion yields exceed binary scaling in the pT range 1 < pT< 4 GeV/c. |

The yields in Au+Au collisions, when scaled by the number of participants, are larger than those measured in the p+p data. The magnitudes of the differences grow with the strangeness of the baryon and with increasing centrality. The enhancements of the Au+Au yields are close to those measured in sqrts = 17.3 GeV collisions. Further, when the binary scaled p+p pT spectra are compared to those of Au+Au the heavy-ion yields exceed binary scaling in the pT range 1 < pT< 4 GeV/c.</abstract><pub>American Physical Society</pub><doi>10.1103/PhysRevC.77.044908</doi><orcidid>https://orcid.org/0000-0001-9611-2004</orcidid><orcidid>https://orcid.org/0000-0001-7547-4241</orcidid><orcidid>https://orcid.org/0000-0002-4684-3121</orcidid><orcidid>https://orcid.org/0000-0002-2039-0590</orcidid><orcidid>https://orcid.org/0000-0003-1825-7907</orcidid><orcidid>https://orcid.org/0000-0001-5920-6271</orcidid><orcidid>https://orcid.org/0000-0002-6611-4380</orcidid><orcidid>https://orcid.org/0000-0003-0687-5580</orcidid><orcidid>https://orcid.org/0000-0001-6413-4479</orcidid><orcidid>https://orcid.org/0000-0003-3069-726X</orcidid><orcidid>https://orcid.org/0000-0002-9781-2632</orcidid><orcidid>https://orcid.org/0000-0003-0687-5580</orcidid><orcidid>https://orcid.org/0000-0002-6611-4380</orcidid></addata></record> |
