Dielectrons as probes for the in-medium structure of hadrons — •Joachim Stroth — GSI Darmstadt and Univ. of Frankfurt

The second generation dielectron spectrometer HADES is designed to study electron pairs emitted in collisions of heavy ions at 1-2 GeV/u as well as in proton and pion induced reactions on protons and nuclei. It went operational at GSI, Darmstadt in November 2001 and has been taking data since for the C+C system at a beam energy of 2 GeV/u and in a commissioning run also for p+p. The objective of the HADES physics program is to establish high statistics invariant mass spectra for various collision systems with a mass resolution of the order of 1 % in the light vector meson mass region.

This presentation will review the physics program of HADES and present the status of the ongoing analysis.
