The NA57 experiment, at the CERN SPS has measured strange baryon and antibaryon production in Pb-Pb collisions with 158 and 40 A GeV/c beam momenta. Recent results on Lambda, Xi and Omega hyperon enhancements and from the transverse mass spectra analysis for the 158 A GeV/c data sample are presented. The energy dependence of hyperon production at mid-rapidity is discussed.

Abstract
The NA57 experiment, at the CERN SPS has measured strange baryon and antibaryon production in Pb-Pb collisions with 158 and 40 A GeV/c beam momenta. Recent results on Lambda, Xi and Omega hyperon enhancements and from the transverse mass spectra analysis for the 158 A GeV/c data sample are presented. The energy dependence of hyperon production at mid-rapidity is discussed.File in questo prodotto:
