Abstract

The CERES experiment (CErenkov Ping Electron Spectrometer) studies the production of low mass e+e- pairs in proton-proton, proton-nucleus and nucleus-nucleus interactions at the CERN SPS. The CERES spectrometer, has a novel design based on two Ping Imaging Cherenkov (RICH) counters, and it operates close to its design specifications. Data were recorded with 200 GeV/u sulfur beam and 450 GeV proton beam. The analysisis in progress. We have extracted first e+e--pairs samples for p+Be, p+Au and S+Au collisions. In addition other physics topics were addressed. Inclusive photon spectra were measured in S+Au interactions. No excess over known hadronic sources was found within our present systematic error of 11%. Results on high pt charged pion spectra are presented up to 4 GeV/c. We also studied the production of e+e--pairs in the strong electromagnetic fields of very peripheral S+Pt collisions. The data are well described by a first-order perturbative QED-calculation.
