Hyperon physics at HADES as a fair phase-0 experiment

FAIR phase-0, hyperon electromagnetic decays, straw tube (tracker)Abstract
The HADES experiment investigates the nuclear matter and the properties of baryonic resonances. As part of the FAIR Phase-0 program, HADES is being upgraded to enable a wide range of experiments, including investigating electromagnetic decays of hyperons produced in proton-induced reactions. Feasibility studies show that the newly installed forward detectors are crucial for hyperon reconstruction. The detector upgrade and feasibility studies in preparation for the upcoming beamtimes are presented.
