Abstract
In the past decade narrow line structures have been discovered in the spectra of positrons and electrons emitted in heavy ion collisions by several experimental groups. These peaks have not yet found a satisfactory explanation. Various theoretical models have been proposed to explain the effect. In this contribution we will report on some of the latest theoretical work and discuss models of a new extended, neutral particle decaying into electron-positron pairs.
