O ct 2 00 4 Strange particle production in 158 and 40 A GeV / c Pb - Pb and p - Be collisions
ثبت نشده
چکیده
Results on strange particle production in Pb-Pb collisions at 158 and 40 A GeV/c beam momentum from the NA57 experiment at CERN SPS are presented. Particle yields and ratios are compared with those measured at RHIC. Strangeness enhancements with respect to p-Be reactions at the same beam momenta have been also measured: results about their dependence on centrality and collision energy are reported and discussed.

Recent NA49 results on Λ and φ production in central Pb-Pb collisions at beam energies from 40 to 158 A·GeV are presented. The measurement of strange baryons like Λ(uds), which contain between 30 and 60% of the total strangeness produced, allows to study simultaneously strangeness production and the effect of baryon density in A-A collisions. Essentially half of the ¯ s quarks are contained in ...

Recent NA49 results on Λ, ¯ Λ, Ξ − and ¯ Ξ + production in minimum bias p+p and centrality selected p+Pb collisions at 158 GeV/c, and the results on Λ, ¯ Λ, K + and K − production in central Pb+Pb collisions at 40, 80 and 158 A·GeV are discussed and compared with other available data. By comparing the energy dependence of Λ and ¯ Λ production at mid-rapidity a striking similarity is observed be...
