Indications for the onset of deconfinement in nucleus nucleus collisions / NA49 collaboration
The hadronic final state of central Pb+Pb collisions at 20, 30, 40, 80, and 158 AGeV has been measured by the CERN NA49 collaboration. The mean transverse mass of pions and kaons at midrapidity stays nearly constant in this energy range, whereas at lower energies, at the AGS, a steep increase with beam energy was measured. [...]

We present the 1st results of the event-by-event study of long-range correlations between event mean Pt and charged particle multiplicity using NA49 experimental data in two separated rapidity intervals in 158 A *Ge V Pb Pb collisions at the CERN SPS. Noticeable long range correlations are found. [...]

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. [...]

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. [...]

Critical fluctuations of the proton density in A+A collisions at $158A$ GeV / NA49 Collaboration
Studies of QCD suggest the existence of a critical point in the phase diagram of strongly interacting matter. Close to this point, according to recent theoretical investigations, the net-proton density carries the critical fluctuations of the chiral order parameter. [...]

System-size and centrality dependence of charged kaon and pion production in nucleus-nucleus collisions at 40A GeV and158A GeV beam energy / NA49 Collaboration
Measurements of charged pion and kaon production are presented in centrality selected Pb+Pb collisions at 40A GeV and 158A GeV beam energy as well as in semi-central C+C and Si+Si interactions at 40A GeV. Transverse mass spectra, rapidity spectra and total yields are determined as a function of centrality. [...]

Inclusive production of protons, anti-protons, neutrons, deuterons and tritons in $p$+C collisions at 158 GeV/c beam momentum / NA49 collaboration
The production of protons, anti-protons, neutrons, deuterons and tritons in minimum bias p+C interactions is studied using a sample of 385 734 inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. The data cover a phase space area ranging from 0 to 1.9 GeV/c in transverse momentum and in Feynman x from -0.80 to 0.95 for protons, from -0.2 to 0.4 for anti-protons and from 0.2 to 0.95 for neutrons.

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. [...]

Exclusive $\gamma\gamma \to \mu^{+}\mu^{-}$ production in proton-proton collisions at $\sqrt{s}$ = 7 TeV / CMS Collaboration
A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at $\sqrt{s}$=7 TeV, pp → pμ + μ −p, is reported using data corresponding to an integrated luminosity of 40 pb−1. For muon pairs with invariant mass greater than 11.5 GeV, transverse momentum p T (μ) > 4 GeV and pseudorapidity |η(μ)| < 2.1, a fit to the dimuon p T (μ + μ −) distribution results in a measured cross section of σ(p → pμ + μ −p) = 338+058−055 (stat.) ± 0.16 (syst.) ± 0.14 (lumi.) pb, consistent with the theoretical prediction evaluated with the event generator Lpair.

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