Transverse mass spectra of strange and multiply--strange particles in Pb--Pb collisions at 158 A GeV/c
The WA97 experiment has measured the transverse mass (m sub T) spectra for negative hadrons (h sup -) and strange particles produced at mid-rapidity in Pb-Pb collisions. The increased statistics of analysed data samples allowed us to perform a study of the spectra of K sup 0 sub S , LAMBDA, XI, OMEG...

| description | The WA97 experiment has measured the transverse mass (m sub T) spectra for negative hadrons (h sup -) and strange particles produced at mid-rapidity in Pb-Pb collisions. The increased statistics of analysed data samples allowed us to perform a study of the spectra of K sup 0 sub S , LAMBDA, XI, OMEGA and h sup - as a function of the centrality of the collisions. The data, which correspond to the most central 40% of the total inelastic cross section, have been divided into four centrality classes according to the estimated number of nucleons taking part in the collision. The m sub T spectra, analysed separately for each centrality bin, exhibit only weak (<= 15%) centrality dependence. The deviation of the OMEGA inverse slope from the linear dependence on the particle mass is confirmed even for the most central Pb-Pb collisions. |
