Query: Dilepton Production in Relativistic Heavy Ion Collisions   The present status of our understanding of low mass dilepton production in
relativistic heavy ion collisions is discussed. The focus of the discussion
will be the sensitivity of dilepton measurements to in medium changes of
hadrons and the restoration of chiral symmetry. We will finally discuss how the
presence of strong long wavelength pion modes, i.e. disoriented chiral
condensates can be seen in the dilepton spectrum.
