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. [...]

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. [...]

Centrality and Transverse Momentum Dependence of Collective Flow in 158 A GeV Pb+Pb Collisions Measured via Inclusive Photons / WA98 Collaboration
Directed and elliptic flow of inclusive photons near mid-rapidity in $158 $A GeV Pb+Pb collisions has been studied. The data have been obtained with the photon spectrometer LEDA of the WA98 experiment at the CERN SPS. [...]

Photon flow in 158 A GeV Pb+Pb collisions / WA98 Collaboration
Directed and elliptic flow of pi /sup 0/ decay photons in 158 A GeV Pb+Pb collisions has been studied near midrapidity in an analysis of data obtained with the photon spectrometer LEDA of the WA98 experiment at the CERN SPS. Preliminary results on the rapidity and transverse momentum dependence of the flow have been obtained for various centrality classes for p/sub T/ > 0.2 GeV/c and 2.3 < y < 2.9. [...]

Particle density fluctuations / WA98 Collaboration
Event-by-event fluctuations in the multiplicities of charged particles and photons at SPS energies are discussed. Fluctuations are studied by controlling the centrality of the reaction and rapidity acceptance of the detectors. [...]

Direct photons in WA98 / WA98 Collaboration
A measurement of direct photon production in /sup 208/Pb+/sup 208/Pb collisions at 158 A GeV has been carried out in the CERN WA98 experiment. The invariant yield of direct photons was extracted as a function of transverse momentum in the interval 0.5<P/sub T/<3.3 GeV /c for, peripheral, and 0.5<P/sub T/<4.0 GeV/c for central collisions.
