    "abstract": "Results of the computer simulation of dilepton production from the expanding\npion gas created in ultrarelativistic Pb+Pb 160 GeV/n collisions are presented.\nFinite size of the expanding pion gas influences invariant mass spectrum of\ndileptons. Sensitivity of the shape of dilepton mass spectrum to the initial\nstage of the pion gas is discussed. Second order asymmetry in azimuthal\ndistribution of dileptons is predicted for non-central collisions.\nNon-equilibrium nature of the pion gas expansion is found to exhibit itself in\nrapidity distribution of produced dilepton pairs.",
