HADES

Ion computed tomography (iCT) is an imaging modality for the direct determination of the relative stopping power (RSP) distribution within a patient's body. Usually, this is done by estimating the path and energy loss of ions traversing the scanned volume via a tracking system and a separate residual energy detector. [...]

Title: Neutral Meson Production in Ag+Ag Collisions at 1.58 A GeV with HADES Electromagnetic Calorimeter Author: Alexandr Prozorov Abstract: The Dielectron Spectrometer HADES operating at the SIS18 synchrotron, FAIR/GSI Darmstadt, recently provided new intriguing results on the pro- duction of electron pairs and strangeness from nucleus-nucleus collisions, as well as from elementary reactions, in the energy region of 1 − 2 A GeV. In 2019 the spectrometer was complemented by an electromagnetic calorimeter based on lead- glass modules, which allows us to measure photons and thus study the production of π0 and η mesons via their two-photon decay [...]

The production of $\Sigma^0$ hyperons in proton proton collisions at a beam kinetic energy of 3.5 GeV impinging on a liquid hydrogen target was investigated using data collected with the HADES setup. The total production cross section is found to be $\mathrm{\sigma (pK^{+}\Sigma^{0}) [\mu b] = 17.7 \pm 1.7 (stat) \pm 1.6 (syst)}$. [...]
