A deep understanding of hadronic final-state interactions is central to the analysis and prediction of experimental data sets.
his is important for meson-baryon systems, as already studied in the pion-beam program in the HADES experiment. With the PANDA experiment, this physics program is decisively extended. It will additionally study baryon resonance systems with strandedness, providing a deeper insight into the nature of hadrons.
Such an extension requires a significant theoretical effort, which must take into account the theory of quantum chromodynamics. While there is a huge experimental dataset on the baryon spectrum with zero strandess quantum number, the information on systems with multiple strandess has been quite limited. This will change with phase 1 of PANDA@FAIR.
The challenge for our theoretical support of this program is to extrapolate the QCD resonance spectrum in its strangeness quantum number.
