TL;DR: HADES as discussed by the authors is a versatile magnetic spectrometer aimed at studying dielectron production in pion, proton and heavy-ion-induced collisions, which includes a ring imaging gas Cherenkov detector for electron-hadron discrimination, a tracking system consisting of a set of 6 superconducting coils producing a toroidal field and drift chambers, and a multiplicity and electron trigger array for additional electron hadron discrimination.

TL;DR: In this paper, the emission of e+ e- pairs from C + C collisions at an incident energy of 1 GeV per nucleon has been investigated, and measured production probabilities, spanning from the π0-Dalitz to the ρ / ω invariant mass region, display a strong excess above the cocktail of standard hadronic sources.
