Abstract

The general features of dilepton production from nucleon-nucleon and nucleus-nucleus collisions are discussed. Estimates are made of the thermal production rates arising from incoherent nucleon-nucleon scattering and from two-pion annihilation. It may be possible to infer the pion dispersion relation in hot and dense nuclear matter by measuring the invariant mass distribution of back-to-back electrons and positrons in the center of mass frame in high energy nucleus- nucleus collisions. Comparison to the recent data on p + Be → e +e − X at 4.9 GeV from the Bevalac is made.
