Photon and Eta Production in p+Pb and p+C Collisions at $\sqrt{s_{NN}} = 17.4$ GeV / WA98 Collaboration
Measurements of direct photon production in p+Pb and p+C collisions at $\sqrt{s_\mathrm{NN}} = 17.4\mathrm{GeV}$ are presented. Upper limits on the direct photon yield as a function of $p_\mathrm{T}$ are derived and compared to the results for Pb+Pb collisions at $\sqrt{s_\mathrm{NN}} = 17.3$ GeV. [...]

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. [...]

Source radii at target rapidity from two-proton and two-deuteron correlations in central Pb+Pb collisions at 158 A GeV / WA98 Collaboration
Two-proton and two-deuteron correlations have been studied in the target fragmentation region of central Pb+Pb collisions at 158 A GeV. [...]

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. [...]

Multiplicity Distributions and Charged-neutral Fluctuations / WA98 Collaboration
Results from the multiplicity distributions of inclusive photons and charged particles, scaling of particle multiplicities, event-by-event multiplicity fluctuations, and charged-neutral fluctuations in 158$\cdot A$ GeV Pb+Pb collisions are presented and discussed. A scaling of charged particle multiplicity as $N_{part}^{1.07\pm 0.05}$ and photons as $N_{part}^{1.12\pm 0.03}$ have been observed, indicating violation of naive wounded nucleon model. [...]

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. [...]

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..

Scaling of Particle and Transverse Energy Production in 208Pb+208Pb collisions at 158 A GeV / WA98 Collaboration
Transverse energy, charged particle pseudorapidity distributions and photon transverse momentum spectra have been studied as a function of the number of participants (N_{part}) and the number of binary nucleon-nucleon collisions (N_{coll}) in 158 A GeV Pb+Pb collisions over a wide impact parameter range. A scaling of the transverse energy pseudorapidity density at midrapidity as N_{part}^{1.08 \pm 0.06} and N_{coll}^{0.83 \pm 0.05} is observed. [...]

Search for disoriented chiral condensates in 158.A GeV Pb + Pb collisions / WA98 Collaboration
A detailed analysis of the phase space distributions of charged particles and photons have been carried out using two independent methods. The results indicate the presence of nonstatistical fluctuations in localized regions of phase space..
