 Abstract: In this talk latest results from the analysis of e ‘e--pairs emitted in Pb+Au collisions at, 40 AGeV/c and a combined analysis of all data available at 158 AGeV/c are presented. The enhancement of low-mass e+e - -pairs (mee >0.2 GeV/c2) with respect to the expected yield from hadron decays first reported at 158 AGeV/c is also found at 40 AGeV/c and is mm larger t,here. Comparing to various theoretical models based on ~T+x- annihilation, the data carp only 1x1 reproduced. if the prop&es of the intermediate p in the hot and :ittilsti !urdium are n~otlificd.
