Constraining resonance properties through kaon production in pion-nucleus collisions at low energies

Understand

Hadronic interactions are crucial for the dynamical description of heavy-ion reactions at low collision energies and in the late dilute stages at high collision energies.

• In particular, the properties and decay channels of resonances are an essential ingredient of hadronic transport approaches.
• The HADES collaboration measured particle production in collisions of pions with carbon and tungsten nuclei at $E_\text{kin} = 1.7\,\text{GeV}$.
• Such reactions are of high interest, because they allow to probe the properties of baryonic resonances produced in a much cleaner environment than the usual nucleus-nucleus collisions.
