Energy dependence of $\Lambda$ and $\Xi$ production in central Pb+Pb collisions at 20A,30A,40A,80A, and 158A GeV measured at the CERN Super Proton / NA49 Collaboration
Results on $\Lambda$, $\bar{\Lambda}$, $\Xi^{-}$, and $\bar{\Xi}^{+}$ production in central Pb+Pb reactions at 20A, 30A, 40A, 80A, and 158A GeV are presented. The energy dependence of transverse mass spectra, rapidity spectra, and multiplicities is discussed. [...]

Energy dependence of fluctuations in central Pb+Pb collisions from NA49 at the CERN SPS / NA49 Collaboration
The latest NA49 results on fluctuations of multiplicity and average transverse-momentum analyzed on an event-by-event basis are presented for central Pb+Pb interactions over the whole SPS energy range (20A - 158A GeV). The scaled variance of the multiplicity distribution decreases with collision energy whereas the $\Phi_{p_{T}}$ measure of $$ fluctuations is small and independent of collision energy. [...]

System-size dependence of $\Lambda$ and $\Xi$ production in nucleus-nucleus collisions at 40A and 158A GeV measured at the CERN Super Proton Synchrotron / NA49 Collaboration
Results on Lambda, Anti-lambda, and Xi- production in centrality selected Pb+Pb reactions at 40A and 158A GeV and in near-central C+C and Si+Si reactions at 158A GeV are presented. Transverse mass spectra, rapidity spectra, and multiplicities in dependence of the system size are discussed. [...]

Bose-Einstein correlations of $\pi^{-}\pi^{-}$ pairs in central Pb+Pb collisions at 20A,30A,40A,80A, and 158A GeV / NA49 Collaboration
Measurements of Bose--Einstein correlations of pion pairs in central Pb+Pb collisions were performed with the NA49 detector at the CERN SPS for beam energies of 20A, 30A, 40A, 80A, and 158A GeV. Correlation functions were measured in the longitudinally co-moving "out-side-long" refere nce frame as a function of rapidity and transverse momentum in the forward hemisphere of the reaction. [...]

Upper Limit of D0 Production in Central Pb-Pb Collisions at 158A GeV / NA49 Collaboration
Results are presented from a search for the decays D0 -> Kmin piplus and D0bar -> Kplus pimin in a sample of 3.8x10^6 central Pb-Pb events collected with a beam energy of 158A GeV by NA49 at the CERN SPS. No signal is observed. [...]

$\Omega$ and $\bar{\Omega}$ production in central Pb+Pb collisions at 40 and 158 AGeV / NA49 Collaboration
Results are presented on Omega production in central Pb+Pb collisions at 40 and 158 AGeV beam energy. Given are transverse-mass spectra, rapidity distributions, and total yields for the sum Omega+Antiomega at 40 AGeV and for Omega and Antiomega separately at 158 AGeV. [...]

Energy and centrality dependence of antiproton and proton production in relativistic Pb+Pb collisions at the CERN SPS / NA49 Collaboration
The transverse mass distributions for antiprotons are measured at midrapidity for minimum bias Pb+Pb collisions at 158A GeV and for central Pb+Pb collisions at 20, 30, 40 and 80 A GeV beam energies in the NA49 experiment at the CERN SPS. [...]

Energy dependence of transverse momentum fluctuations in Pb+Pb collisions at the CERN Super Proton Synchrotron (SPS) at 20A to 158A GeV / NA49 Collaboration
Results are presented on event-by-event fluctuations of transverse momenta $p_T$ in central Pb+Pb interactions at 20$A$, 30$A$, 40$A$, 80$A$ and 158$A$ GeV. The analysis was performed for charged particles at forward center-of-mass rapidity ($1.1 < y^{*}_{\pi} < 2.6$). [...]

Energy dependence of $\phi$ meson production in central Pb+Pb collisions at $\sqrt{s_{NN}}$=6 to 17 GeV / NA49 Collaboration
Phi meson production is studied by the NA49 collaboration in central Pb+Pb collisions at 20A, 30A, 40A, 80A and 158A GeV beam energy. The data are compared to measurements at lower and higher energies and to microscopic and thermal models. [...]

Antideuteron and deuteron production in mid-central Pb+Pb collisions at 158$A$ GeV / NA49 collaboration
Production of deuterons and antideuterons was studied by the NA49 experiment in the 23.5% most central Pb+Pb collisions at the top SPS energy of $\sqrt{s_{NN}}$=17.3 GeV. Invariant yields for $\bar{d}$ and $d$ were measured as a function of centrality in the center-of-mass rapidity range $-1.2<y<-0.6$. [...]
