    "abstract": "The mass spectrum is calculated for those dileptons which are produced in the\nearly phase of a heavy ion collisions via the direct production NN -\u003e\n(l^+)(l^-)X and via the Compton process GN -\u003e (l^+)(l^-)X with prompt gluons\nradiated in preceding NN interactions. Both mechanisms produce a mass spectrum\nwhich decreases steeply with invariant mass of the l^+l^- pair and which is\nbelow the CERES data for Pb-Au collisions by about one order of magnitude.",
