    "abstract": "Disoriented chiral condensates or long wavelength pionic oscillations and\ntheir interaction with the thermal environment can be a significant source of\ndileptons. We calculate the yield of such dilepton production within the linear\nsigma model, both in a quantal mean-field treatment and in a semi-classical\napproximation. We then illustrate the basic features of the dilepton spectrum\nin a schematic model. We find that dilepton yield with invariant mass near and\nbelow $2m_{\\pi}$ due to the soft pion modes can be up to two orders of\nmagnitude larger than the corresponding equilibrium yield.",
