One-, two-, and three-particle distributions from 158A GeV/c central Pb+Pb collisions.

Original language description

Several hadronic observables have been studied in central 158A GeV Pb+Pb collisions using data measured by the WA98 experiment at CERN: single pi(-) and K- production, as well as two- and three-pion interferometry. The Wiedemann-Heinz hydrodynamical model has been fitted to the pion spectrum, giving an estimate of the temperature and transverse flow velocity. Bose-Einstein correlations between two identified pi(-) have been analyzed as a function of k(T), using two different parametrizations. The results indicate that the source does not have a strictly boost invariant expansion or spend time in a long-lived intermediate phase. A comparison between data and a hydrodynamical based simulation shows very good agreement for the radii parameters as a function of k(T). The pion phase-space density at freeze-out has been measured, and agrees well with the Tomasik-Heinz model. A large pion chemical potential close to the condensation limit of m(pi) seems to be excluded. The three-pion Bose-Ein
