Abstract
An enhanced production of dileptons -e(+)e(-) or mu(+)mu(-) pairs-, ov er those expected from known hadronic sources, has been observed by CE RES, HELIOS-3 and NA38 in S-induced interactions on heavy targets at 2 00 GeV/nucleon. The excess covers the mass range from 200 MeV/c(2) up to the J/psi. There is no clear evidence of a signal in the search for direct photons. All the experimental results seem to be fairly consis tent.
