New Ceres Results
Abstract
During 1999 the CERES experiment upgraded by the new TPC was taking data from semicentral Pb+Au collisions at 40 AGeV. The analysis of the di-electron spectra shows an enhancement in the low mass region of at least the same magnitude as previously observed at full SPS energy. The results are compared to model calculations with and without medium modifications of the vector mesons. The addition of the radial TPC gives more possibilities to study hadronic observables. The results obtained for the midrapidity Lambda yield and the AntiLambda/Lambda ratio are compared to the existing systematics
