Transverse mass spectra of strange and multi-strange particles in Pb-Pb collisions at 158 A GeV/c
The WA97 experiment has measured the transverse mass (\mT) spectra fornegative hadrons (\hneg) 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 \PKzS, \PgL, $\mathrm{\Xi}$, $\mathrm...

| description | The WA97 experiment has measured the transverse mass (\mT) spectra fornegative hadrons (\hneg) 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 \PKzS, \PgL, $\mathrm{\Xi}$, $\mathrm{\Omega}$ and\hneg~as a function of the collision centrality. The data, whichcorrespond to the most central 40\% of the total inelastic cross section,have been divided into four centrality classes according to the estimated numberof nucleons taking part in the collision. The \mT~ spectra, analysed separatelyfor each centrality bin, exhibit only weak ($\leq$ 15\%) centrality dependence. The deviation of the$\mathrm{\Omega}$ inverse slope from the linear dependence on the particle massis confirmed even for the most central Pb--Pb collisions. |
