Algorithmic improvements and the power of modern high performance computers have enabled simulations around and even below physical light sea quark masses. At these quark mass values most hadrons become unstable and scattering states need to be considered, also in view of other CRC-TRR projects. Moreover, the study of resonances themselves is at the focus of major experiments, e.g., glueX at Jefferson Lab and some scattering parameters are of central importance for effective field theory descriptions of light hadrons and their interactions. Here we will compute from first principles QCD these parameters for several decay channels at realistic quark mass values.
