Recent results from the CERES/NA45 experiment and upgrade with a radial-drift TPC
The CERES/NA45 experiment measures low mass electron pair production in Pb - Au collisions at 158A GeV at the CERN SPS. In this paper, we present the electron pair enhancement in the mass range $0.2<m_{ee}$ < 0.7 GeV/c$^{2}$, it increases more than linear with charged multiplicity and is most...

| description | The CERES/NA45 experiment measures low mass electron pair production in Pb - Au collisions at 158A GeV at the CERN SPS. In this paper, we present the electron pair enhancement in the mass range $0.2<m_{ee}$ < 0.7 GeV/c$^{2}$, it increases more than linear with charged multiplicity and is most pronounced at low pair $p_{T}$ < 0.5 GeV/c. Transverse mass and rapidity distributions for charged hadrons $h^{+}-h^{-}$ and azimuthal event anisotropies ( $\upsilon_{1}/, \upsilon_{2}$) of charged particles are shown as a function of centrality. Finally, we present the status of the upgrade with a radial-drift TPC. |
