    "abstract": "We show that the coherent oscillations of the e.m. field induced by the\ncollective quantum fluctuations of the nuclear matter field associated with the\ngiant resonances, with frequencies $\\omega_{A}\\simeq 78A^{-{1/3}}$ MeV, give\nrise to a significant $(e^+e^-)$ pair production in high energy Heavy Ion\ncollisions. The approximate parameterless calculation of such yield is in good\nagreement with recent experimental observations.",
