Three-Pion Interferometry Results from Central Pb+Pb Collisions at 158 A GeV/c / WA98 Collaboration
Three-particle correlations have been measured for identified negative pions from central 158 A GeV Pb+Pb collisions by the WA98 experiment at CERN. A substantial contribution of the genuine three-body correlation has been found as expected for a mainly chaotic and symmetric source..

Freeze-Out Parameters in Central 158 AGeV $^{208}Pb$ + $^{208}Pb$ Collisions / WA98 Collaboration
Neutral pion production in central 158AGeV Pb+Pb collisions has been studied in the WA98 experiment at the CERN SPS. The pi0 transverse mass spectrum has been analyzed in terms of a thermal model with hydrodynamic expansion. [...]

Localized Charged-Neutral Fluctuations in 158 A GeV Pb+Pb Collisions / WA98 Collaboration
First results on the measurement of localized fluctuations in the multiplicity of charged particles and photons produced in central 158 A GeV Pb+Pb collisions are presented. The charged versus neutral correlations in common phase space regions of varying azimuthal size are analyzed by two different methods. [...]

Observation of Direct Photons in Central 158 A GeV $^{208}Pb+^{208}Pb$ Collisions / WA98 Collaboration
A measurement of direct photon production in 208Pb + 208Pb collisions at 158 A GeV has been carried out in the CERN WA98 experiment. The invariant yield of direct photons in central collisions is extracted as a function of transverse momentum in the interval 0.5 < p_T < 4 GeV/c. [...]

Centrality Dependence of Neutral Pion Production in 158 A GeV $^{208}Pb +^{208}Pb$ Collisions / WA98 Collaboration
The production of neutral pions in 158AGeV Pb+Pb collisions has been studied in the WA98 experiment at the CERN SPS. Transverse momentum spectra are studied for the range 0.3 GeV/c < mT-m0 < 4.0 GeV/c. [...]

Event-by-event charged-neutral fluctuations in Pb+Pb collisions at 158 A~GeV / WA98 Collaboration
Charged particles and photons have been measured in central Pb+Pb collisions at 158 A GeV in a common ($\eta$ - $\phi$)-phase space region in the WA98 experiment at the CERN SPS. The measured distributions have been analyzed %using the sliding window method in order to quantify the frequency with which phase space regions of varying sizes have either small or large neutral pion fraction.

Suppression of High-pT Neutral Pions in Central Pb+Pb Collisions at sqrt{s_NN} = 17.3 GeV / WA98 Collaboration
Neutral pion transverse momentum spectra were measured in p+C and p+Pb collisions at sqrt{s_NN} = 17.4 GeV at mid-rapidity (2.3 <eta < 3.0) over the range 0.7 <p_T < 3.5 GeV/c. The spectra are compared to neutral pion spectra measured in Pb+Pb collisions at the same energy in the same experiment. [...]

Pion Freeze-Out Time in Pb+Pb Collisions at 158 A GeV/c Studied via pi-/pi+ and K-/K+ Ratios / WA98 Collaboration
The effect of the final state Coulomb interaction on particles produced in Pb+Pb collisions at 158 A GeV/c has been investigated in the WA98 experiment through the study of the pi-/pi+ and K-/K+ ratios measured as a function of transverse mass. While the ratio for kaons shows no significant transverse mass dependence, the pi-/pi+ ratio is enhanced at small transverse mass values with an enhancement that increases with centrality. [...]
