High Data Quality
The data quality in terms of statistics, mass resolution and particle identifcation allow for precise measurements in various fields of hadron physics.
• Systematic studies of e+e- production in nucleon-nucleon and heavy-ion collisions resulting in an isolation of true in-medium effects.
• First observation of omega signal in e+e- decay channel at SIS18 energies in proton (see figure) and heavy-ion induced reactions.
• Hyperon (Σ(1385) and Λ(1405)) production in proton-proton reactions.
• Strangeness production (ϕ, K+/-, Ξ(1321)) in heavy-ion collsions.
