Title
Results on Hyperon production from NA57 experiment
Abstract
The NA57 experiment at CERN SPS has been specifically designed to study the onset of the strange baryon and antibaryon enhancements in PbPb with respect to pBe collisions, first observed by the WA97 experiment at 160 A GeV/c beam momentum. The aim is to look for the dependence of these enhancements on the interaction volume, as measured by the number of wounded nucleons, and the energy per incoming nucleon. Compared with WA97, in NA57 the centrality range goes down to a lower limit of about 50 wounded nucleons, was about 100 in WA97, and data have been collected both at 160 and at 40 A GeV/c, while WA97 collected data only at the top SPS beam momentum of 160 A GeV/c. In this contribution we present the results on strange baryon production and the status of the forthcoming analysis.
