The CERES/NA45 radial drift Time Projection Chamber / CERES Collaboration
The design, calibration, and performance of the first radial drift Time Projection Chamber (TPC) are presented. The TPC was built and installed at the CERES/NA45 experiment at the CERN SPS in the late nineties, with the objective to improve the momentum resolution of the spectrometer. [...]

New results on Pb - Au collisions at 40 AGeV from the CERES/NA45 experiment / NA45 Collaboration
In 1999 the CERES/NA45 ran at the CERN SPS with a beam energy of 40 GeV/nucleon. The data set comprises about 8.7 millions Pb-Au events with a trigger selection corresponding to approximately the most central 30% of the geometrical cross section. [...]

Triangular flow of negative pions emitted in PbAu collisions at $\sqrt{S_{NN}} = 17.3$ GeV / for the CERES/NA45 collaboration
Differential triangular flow, $v_3(p_T)$, of negative pions is measured at $\sqrt{s_{NN}}$= 17.3~GeV around midrapidity by the CERES/NA45 experiment at CERN in central PbAu collisions in the range 0-30\% with a mean centrality of 5.5\%. This is the first measurement of the triangular flow at SPS energies. [...]

Azimuthal dependence of pion source radii in Pb + Au collisions at 158 A GeV / CERES Collaboration
We present results of a two-pion correlation analysis performed with the Au+Pb collision data collected by the upgraded CERES experiment in the fall of 2000. The analysis was done in bins of the reaction centrality and the pion azimuthal emission angle with respect to the reaction plane. [...]

Dilepton measurements with CERES / CERES Collaboration
We report on dilepton measurements for central Pb on Au collisions at the top CERN SPS energy with the upgraded CERES experiment. The dilepton mass spectrum of 2000 data with improved mass resolution shows an enhancement over the expectation from hadron decays that is well described by a model including a strong broadening of the $\rho$ spectral function.

Modification of the $\rho$-meson detected by low-mass electron-positron pairs in central Pb - Au collisions at 158 A GeV/c / CERES Collaboration
We present a measurement of $e^+e^-$ pair production in central Pb-Au collisions at 158$A$ GeV/$c$. As reported earlier, a significant excess of the $e^+e^-$ pair yield over the expectation from hadron decays is observed. [...]

The $v^{1/3}_{3}/v^{1/2}_{2}$ ratio in PbAu collisions at $\sqrt{s_{\textrm{NN}}} = $ 17.3 GeV: a hint of a hydrodynamic behavior / CERES NA45 Collaboration
The Fourier harmonics, $v_2$ and $v_3$ of negative pions are measured at center-of-mass energy per nucleon pair of $\sqrt{s_{\mathrm{NN}}}$= 17.3 GeV around midrapidity by the CERES/NA45 experiment at the CERN SPS in 0--30% central PbAu collisions with a mean centrality of 5.5%. The analysis is performed in two centrality bins as a function of the transverse momentum $\mathrm{p_{\mathrm{T}}}$ from 0.05 GeV/$c$ to more than 2 GeV/$c$. [...]

Beam energy and centrality dependence of two-pion Bose-Einstein correlations at SPS energies / CERES Collaboration
Results are presented of a two-pion interferometry (HBT) analysis in Pb+Au collisions at 40, 80, and 158 AGeV. A detailed study of the Bertsch-Pratt HBT radius parameters has been performed as function of the mean pair transverse momentum $k_t$ and in bins of the centrality of the collision. [...]
