Strangeness enhancements at central rapidity in 40 A GeV/c Pb-Pb collisions
The NA57 Collaboration, F. Antinori
Results are presented on neutral kaon, hyperon and antihyperon production in Pb-Pb and p-Be interactions at 40 GeV/c per nucleon. The enhancement pattern follows the same hierarchy…
Expansion dynamics of Pb-Pb collisions at 40 A GeV/c viewed by negatively charged hadrons
The NA57 Collaboration
In this paper we present results on transverse mass spectra and Hanbury-Brown and Twiss correlation functions of negatively charged hadrons, which are expected to be mostly negativ…
Transverse dynamics of Pb-Pb collisions at 40 A GeV/c viewed by strange hadrons
The NA57 Collaboration
The transverse mass spectra of K0s, Lambda, Xi and Omega particles produced in Pb-Pb collisions at 40 A GeV/c have been studied for a sample of events corresponding to the most cen…
Central-to-peripheral nuclear modification factors in Pb-Pb collisions at sqrt{s_NN} = 17.3 GeV
NA57 Collaboration
We present central-to-peripheral nuclear modification factors, R_CP, for the p_T distributions of K^0_S, Lambda, Anti-Lambda, and negatively charged particles, measured at central…
Multiplicity of charged particles in Pb-Pb collisions at SPS energies
The NA57 collaboration
The multiplicity of charged particles in the central rapidity region has been measured by the NA57 experiment in Pb--Pb collisions at the CERN SPS at two beam momenta: 158 A GeV/{\…
Energy dependence of {\rm K} and hyperon production at CERN SPS
D Elia
Recent results on K and hyperon production in Pb-Pb collisions at 40 and 158 GeV/ beam momentum from the NA57 experiment at CERN SPS are presented. Yields and ra…
