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. [...]

One-, two- and three-particle distributions from central Pb+Pb collisions at 158A GeV/c / WA98 Collaboration
The WA98 experiment at the CERN SPS combines large acceptance photon detectors with a two-arm charged particle tracking spectrometer to study 158A GeV Pb+Pb collisions.We present results from one-, two- and three-particle analyses for charged particles identified with a time of flight system. The rapidity acceptance for pions in the first (second) arm ranged from y=2.1 (2.6) to 3.1 (3.8) with an average at 2.7 (3.2), close to mid-rapidity which was 2.9. [...]

Recent results from the WA98 experiment / WA98 Collaboration
Recent results of the WA98 experiment with Pb induced reactions at 158.A GeV are presented. The scaling properties of the transverse energy and the charged particle multiplicity at midrapidity with the number of participants is studied. [...]

Collective flow and HBT in Pb+Pb collisions at the CERN-SPS / WA98 Collaboration
Study of elliptic emission for identified particles has been performed in 158A GeV Pb+Pb collisions near mid-rapidity region. Our preliminary results indicate the existence of the in-plane elliptic emission for pi /sup +/ and proton, and out-of-plane elliptic emission for K/sup +/ in semi-central collisions. [...]

Elliptic emission of $K^{+}$ and $\pi^{+}$ in 158A GeV Pb + Pb collisions / WA98 Collaboration
An event-by-event analysis of the azimuthal angular correlation with respect to the reaction plane has been carried out for K/sup +/ and pi /sup +/ emission near mid-rapidity in 158A.GeV Pb+Pb collisions. In semi-central collisions, K/sup +/ mesons are found to be preferentially emitted out of the reaction plane, while pi /sup +/ mesons are emitted in the reaction plane. [...]

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.
