New Ceres Results
During 1999 the CERES experiment upgraded by the new TPC was taking data from semi-central 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...

متن کاملNew results from CERES 2 beam UV detector
During the year 2000 the CERES experiment, upgraded with a radial drift TPC, took a large data sample of Pb on Au collisions at 158 AGeV triggered on the 8% most central collisions. A very detailed calibration of the radial drift TPC was since completed. Preliminary results on e + e − pairs and φ mesons reconstructed in the K + K − channel are presented.

متن کاملCollection of Ceres Results
CERES is a dilepton experiment at the CERN SPS, known for its observation of enhanced production of low mass ee pairs in collisions between heavy nuclei [ 1]. The fact that the excess pairs had invariant masses above approximately twice the pion mass and that the enhancement was absent in proton induced collisions [ 2] pointed towards pion annihilation ππ → ρ → ee as the additional source of le...
