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. [...]

$\Omega$ 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 dependence of multiplicity fluctuations in heavy ion collisions at 20A to 158A GeV / NA49 Collaboration
Multiplicity fluctuations of positively, negatively and all charged hadrons in the forward hemisphere were studied in central Pb+Pb collisions at 20A, 30A, 40A, 80A and 158A GeV. The multiplicity distributions and their scaled variances $\omega$ are presented in dependence of collision energy as well as of rapidity and transverse momentum. [...]

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. [...]

Electric charge fluctuations in central Pb+Pb collisions at 20A, 30A, 40A, 80A, and 158A GeV / NA49 Collaboration
Results are presented on event-by-event electric charge fluctuations in central Pb+Pb collisions at 20, 30, 40, 80 and 158 AGeV. The observed fluctuations are close to those expected for a gas of pions correlated by global charge conservation only. [...]

System size and centrality dependence of the balance function in $A+A$ collisions at $\sqrt s_{NN} = 17.2$ GeV / NA49 Collaboration
Electric charge correlations were studied for $p+p$, C+C, Si+Si and centrality selected Pb+Pb collisions at $\sqrt{s_{NN}} = 17.2$ GeV with the NA49 large acceptance detector at the CERN-SPS. In particular, long range pseudo-rapidity correlations of oppositely charged particles were measured using the Balance Function method. [...]

$\Lambda$ 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. [...]

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 $-1.2<y<-0.6$. [...]

Rapidity and energy dependence of the electric charge correlations in A+A collisions at the SPS energies / NA49 Collaboration
Results from electric charge correlations studied with the Balance Function method in A+A collisions from 20A to 158A GeV are presented in two different rapidity intervals: In the mid-rapidity region we observe a decrease of the width of the Balance Function distribution with increasing centrality of the collision, whereas this effect vanishes in the forward rapidity region. Results from the energy dependence study in central Pb+Pb collisions show that the narrowing of the Balance Function expressed by the normalised width parameter \textit{W} increases with energy towards the highest SPS and RHIC energies.

Proton - Lambda Correlations in Central Pb+Pb Collisions at $\sqrt{s_{NN}}$ = 17.3 GeV / NA49 Collaboration
The momentum correlation between protons and lambda particles emitted from central Pb+Pb collisions at sqrt(s_{NN}) = 17.3 GeV was studied by the NA49 experiment at the CERN SPS. A clear enhancement is observed for small relative momenta (q_{inv} < 0.2 GeV). [...]
