Preliminary results from the 2000 run of CERES on low-mass $e^{+}e^{-}$ pair production in Pb - Au collisions at 158 A GeV
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....
