“…, and Λ → π + p. The selection procedure is described in detail in [ 9]. The main criteria are the following: (a) the two decay tracks are compatible with the hypothesis of having a common origin point; (b) the reconstructed secondary vertex is well separated from the target; (c) the reconstructed candidate points back to the primary vertex position.…”

“…The study of R CP and of its particle-species dependence, in particular the meson/baryon dependence, at top SPS energy allows to test for these phenomena at an energy smaller by about one order of magnitude ( √ s NN = 17.3 GeV). While measurements of the π 0 R CP by the WA98 Collaboration, supporting the presence of parton energy loss effects, were published already in 2002 [ 8], the first results on the particle-species dependence (unidentified negatively charged hadrons, K 0 S , Λ, and Λ) have been reported by the NA57 Collaboration in [ 9].…”

“…Similar to what has been seen at RHIC, the away-side peaks broadens with centrality, which might be attributed to in-medium effects. Recently, new data on R CP for identified particles have been presented by the NA49 and NA57 experiment [9,10]. Additionally, the NA45 collaboration has done a refined analysis of two particle azimuthal correlations at high p t [11].…”

High pT Measurements at the CERN SPS

The current experimental situation concerning high p t observables at the CERN SPS is reviewed. Recent data from the NA45, NA49 and NA57 collaborations are discussed and compared to earlier measurements by WA98 and NA45 at the same center-of-mass energies, as well as to measurements at the higher energies by the RHIC experiments. The observables include new p+p, A+A spectra, nuclear modification factors (R AA , R CP ), two particle azimuthal correlations, and baryon to meson ratios at moderately high p t . Generally, the interpretation of the SPS data suffers from the lack of reliable baseline measurements (p+p and p+A). However, the overall picture that is emerging suggests that already at SPS energies medium effects similar to those observed at RHIC are present.

“…We have compared our results with perturbative-QCD-based theoretichal predictions [19,20] with and without in-medium energy loss, which include the initial-state partonic intrinsic p broadening tuned on the original Cronin effect data [21]. The calculations with in-medium energy loss describe the data much better [14].…”

Abstract. The NA57 experiment at the CERN SPS has measured the production of strange and multi-strange particles in Pb-Pb (and p-Be) collisions at mid-rapidity. The collective dynamics of the collision is studied in the transverse and longitudinal directions as a function of centrality and beam momentum and analysed based on hydrodynamical models. Central-to-peripheral nuclear modification factors at 158 A GeV/c are presented and compared with other measurements and theory.
