Description

CERES has measured low-mass e+e- pairs in Pb-Au collisions at 158 A GeV in the year 2000 Pb run at the SPS with the goal of shedding more light on the origin of the previously observed low-mass pair enhancement. The spectrometer was upgraded with a radial TPC to improve the mass resolution. A very effective rejection of the combinatorial background is achieved using the combined information of the two RICH detectors, the dE/dx signal of the doublet of silicon drift chambers, and the TPC track dE/dx information. Various steps and the current status of the data analysis are presented
