Strange particle production p-Be, p-Pb, Pb-Pb at 158 A GeV/c (WA97 experiment)

The CERN experiment WA97, which studies strange particle production at central rapidity in Pb-Pb, p-Pb, p-Be collisions at 158 A GeV/c, has already reported a pronounced enhancement of hyperon production. This is considered as a sensitive signature for a phase transition to a new state of matter-the...

Descripción
Sumario:The CERN experiment WA97, which studies strange particle production at central rapidity in Pb-Pb, p-Pb, p-Be collisions at 158 A GeV/c, has already reported a pronounced enhancement of hyperon production. This is considered as a sensitive signature for a phase transition to a new state of matter-the quark gluon plasma (QGP). A comprehensive study, including the most recent results, of yields and transverse mass spectra of K/sub S//sup 0/, Lambda , Xi /sup -/, Omega /sup -/ (and antiparticles) and negative particles as a function of the number of nucleons participating in the collisions is presented. (11 refs).
