Energy dependence of hadronic observables in central Pb+Pb reactions at the CERN SPS / NA49 Collaboration
In this contribution the energy dependence of various hadronic observables as measured by the NA49 experiment in the beam energy range between 20 and 158A GeV is presented. These include $m_{t}$ and rapidity distributions, particle ratio fluctuations, as well as HBT radii. [...]

New results from NA49 / NA49 Collaboration
Recent results of the NA49 experiment are presented. These cover first results on pion and kaon production, HBT, and charge fluctuations from Pb+Pb reactions at 40 AGeV and their comparison to 158 AGeV beam energy. [...]

Deuteron production in central Pb+Pb collisions at 158A GeV / NA49 Collaboration
Experimental results on deuteron emission from central Pb+Pb collisions (E/sub beam/=158A GeV, fixed target), obtained by NA49 at the CERN SPS accelerator, are presented. The transverse mass m/sub t/ distribution was measured near mid-rapidity (2.0<y<2.5) in the range of 0<m/sub t/-m/sub 0/<0.9 GeV/c/sup 2/ (0<p/sub t/<2.0 GeV/c) for the 4% most central collisions.

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. [...]

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. [...]

Indications for the onset of deconfinement in Pb + Pb collisions at the CERN SPS from NA49 / Seyboth, P ; Alt, C ; Anticic, T ; Baatar, B ; Barna, D ; Bartke, Jerzy ; Betev, L ; Bialkowska, H ; Blume, C ; Boimska, B et al.
Particle production in central Pb+Pb collisions was studied with the NA49 large acceptance spectrometer at the CERN SPS at beam energies of 20, 30, 40, 80, and 158 GeV per nucleon. A change of the energy dependence is observed around 30A GeV for the yields of pions and strange particles as well as for the shapes of the transverse mass spectra. [...]

Correlations and fluctuations in Pb+Pb collisions / NA49 Collaboration
Results on two-particle correlations, deuteron production, event anisotropy and event-by-event fluctuations of <p/sub T/> and K/ pi were obtained by the NA49 experiment in Pb+Pb collisions at 158 A.GeV beam energy. The interpretation of the measurements is discussed in light of the search for deconfinement. [...]

Evidence for the onset of deconfinement and quest for the critical point by NA49 at the CERN SPS / NA49 Collaboration
The NA49 results on hadron production obtained in PbPb collisions at SPS energies from 20 to 158 A GeV are shown and discussed as evidence for the onset of deconfinement. The primary measures are the pion yield, the kaon-to-pion ratio and the slope parameter of transverse mass distributions. [...]
