Transverse Momentum Fluctuations in Nuclear Collisions at 158A GeV / NA49 Collaboration
Results are presented on event-by-event fluctuations in transverse momentum of charged particles, produced at forward rapidities in p+p, C+C, Si+Si and Pb+Pb collisions at 158A GeV. Three different characteristics are discussed: the average transverse momentum of the event, the $\Phi_{PT}$ fluctuation measure and two-particle transverse momentum correlations. [...]

Observation of an Exotic S = -2, Q = -2 Baryon Resonance in Proton-Proton Collisions at the CERN SPS / NA49 Collaboration
Results of resonance searches in the $\Xi^{-} \pi^{-}, \Xi^{-} \pi^{+}, \bar{Xi}^{+} \pi-$ and $\bar{Xi}^{+} \pi^{+}$ invariant mass spectra in proton-proton collisions at $\sqrt{s}=17.2$ GeV are presented. Evidence is shown for the existence of a narrow $\Xi^{-} \pi^{-}$ baryon resonance with mass of 1.862+/-0.002 GeV/c^2 and width below the detector resolution of about 0.018 GeV/c^2. [...]

Multistrange Hyperon Production in Pb+Pb collisions at 30, 40, 80 and 158 A$\cdot$GeV / NA49 Collaboration
A non-monotonic energy dependence of the $K^{+} / \pi^{+}$ ratio with a sharp maximum close to 30 A$\cdot$GeV is observed in central Pb+Pb collisions. Within a statistical model of the early stage, this is interpreted as a sign of the phase transition to a QGP, which causes a sharp change in the energy dependence of the strangeness to entropy ratio. [...]

$\Lambda$ and $\bar{\Lambda}$ production in central Pb-Pb collisions at 40, 80, and 158A GeV / NA49 Collaboration
Production of Lambda and Antilambda hyperons was measured in central Pb-Pb collisions at 40, 80, and 158 A$\cdot$GeV beam energy on a fixed target. Transverse mass spectra and rapidity distributions are given for all three energies. [...]

Evidence for an exotic S=-2, Q=-2 baryon resonance in proton-proton collisions at the CERN SPS / NA49 Collaboration
Results of resonance searches in the $\Xi^{-} \pi^{-}, \Xi^{-} \pi ^{+}, \bar{\Xi}^{+} \pi^{-}$, and $\bar{\Xi}^{+} \pi^{+}$ invariant mass spectra in proton-proton collisions at $\sqrt s =17.2$ GeV are presented. Evidence is shown for the existence of a narrow $\Xi^{-} \pi^{-}$ baryon resonance with mass of 1.862$\pm$0.002 GeV/$c^{2}$ and width below the detector resolution of about 0.018 GeV/$c^{2}$. [...]

Strangeness from 20-A-GeV to 158-A-GeV / NA49 Collaboration
New results from the energy scan programme of NA49, in particular kaon production at 30 AGeV and phi production at 40 and 80 AGeV are presented. The K+/pi+ ratio shows a pronounced maximum at 30 AGeV; the kaon slope parameters are constant at SPS energies. [...]

Directed and elliptic flow of charged pions and protons in Pb+Pb collisions at 40 and 158 AGeV / NA49 Collaboration
Directed and elliptic flow measurements for charged pions and protons are reported as a function of transverse momentum, rapidity, and centrality for 40 and 158 AGeV Pb + Pb collisions as recorded by the NA49 detector. Both the standard method of correlating particles with an event plane, and the cumulant method of studying multiparticle correlations are used. [...]

Bose-Einstein Correlations of Charged Kaons in Central Pb+Pb Collisions at $E_{beam} = 158 AGeV$ / NA49 Collaboration
Bose-Einstein correlations of charged kaons were measured near mid-rapidity in central Pb+Pb collisions at 158 A$\cdot$GeV by the NA49 experiment at the CERN SPS. Source radii were extracted using the Yano-Koonin-Podgoretsky and Bertsch-Pratt parameterizations [...]
