New results from CERES

We will focus here on results from the 1999 data taking period, where 8 M Pb+Au events at 40 AGeV were recorded. Since the new readout system of the TPC was not yet properly working, this data set is limited in terms of statistics, and momentum resolution. Nevertheless, this data sample at lower bea...

Sumario:We will focus here on results from the 1999 data taking period, where 8 M Pb+Au events at 40 AGeV were recorded. Since the new readout system of the TPC was not yet properly working, this data set is limited in terms of statistics, and momentum resolution. Nevertheless, this data sample at lower beam energy allows to study initial conditions different from the ones at top SPS energy. This can be very useful to disentangle temperature and baryon density driven modifications of the dilepton spectrum. (15 refs).
