System size dependence of particle-ratio fluctuations in Pb+Pb collisions at 158$A$ GeV / NA49 collaboration
New measurements by the NA49 experiment of the centrality dependence of event-by-event fluctuations of the particle yield ratios (K$^{+}$+K$^{-}$)/($\pi^{+}+\pi^{-}$), (p+$\bar{\text p}$)/($\pi^{+}+\pi^{-}$), and (K$^{+}$+K$^{-}$)/(p+$\bar{\text p}$) are presented for Pb+Pb collisions at 158$A$ GeV. The absolute values of the dynamical fluctuations of these ratios, quantified by the measure $\sigma_{\text{dyn}}$, increase by about a factor of two from central to semi-peripheral collisions. [...]

Onset of deconfinement and search for the critical point of strongly interacting matter at CERN SPS energies / for the NA49 collaboration
The exploration of the QCD phase diagram particularly the search for a phase transition from hadronic to partonic degrees of freedom and possibly a critical endpoint, is one of the most challenging tasks in present heavy-ion physics. As observed by the NA49 experiment, several hadronic observables in central Pb+Pb collisions at the CERN SPS show qualitative changes in their energy dependence. [...]

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

Energy dependence of kaon-to-proton ratio fluctuations in central Pb+Pb collisions from $\sqrt{s_{NN}}$ = 6.3 to 17.3 GeV / NA49 Collaboration
Kaons and protons carry large parts of two conserved quantities, strangeness and baryon number. It is argued that their correlation and thus also fluctuations are sensitive to conditions prevailing at the anticipated parton-hadron phase boundary. [...]
