Abstract:
The HADES experiment, installed at GSI, Darmstadt, measures di-electron production in A + A, p/π + N and p/π + A collisions. Here, the π 0 and η Dalitz decays have been reconstruced in the exclusive p + p reaction at 2.2 GeV to form a reference cocktail for long-lived di-electron sources. In the C + C reaction at 1 and 2 GeV/u, these long-lived sources have been subtracted from the measured inclusive e + e - yield to exhibit the signal from the early phase of the collision. The results suggest that resonances play an important role in dense nuclear matter.
