Reconstruction of Exclusive Channels in Elementary Reactions with HADES. — •Tiago Pérez — II Physikalisches Institut, Heinrich-Buff-Ring 16, 35392, Gießen.
For the HADES experiment, which investigates the dilepton production in heavy ions reactions at GSI, the thorough understanding of the elementary sources, as well as the detector efficiency is crucial to explain the dilepton spectra of heavy ions at medium energy, from 1 to 2 GeV per nucleon.
In the year 2004 HADES has had its first production proton-proton run with a beam of 2.2 GeV kinetic energy.
The comparison between the different decay channel of the η meson, thanks to the known relative branching ratios of the hadronic, η → π+π−π0, and Dalitz, η → e+e−γ, decays will provide an important tool to understand the efficiency of our detector.
The first results of exclusive reconstruction of the η hadronic decay channel with HADES as well as the analysis methodology will be presented.
