Abstract

The general features of electron-positron emission from high temperature nuclear matter are discussed. Estimates are made of the 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.

Bibliographical note

Funding Information:
quark-gluon plasma formation is expected. The argument is simply that whenever charged objects collide they radiate real and virtual photons, the virtual photons decaying into dilepton pairs. The advantage of observing electromagnetic signals from a strongly interacting many-body system is that they travel relatively unscathed from the production point to the detector. Since production rates are rapidly increasing functions of *Supported by the 8.S. DOE under contract NSERC of Canada. Speaker_
