Prof. Christian Lang


It took more than 40 years until Lattice QCD tools have become evolved far
enough to address excited hadrons in a reliable way. Still, we are confined to
the low lying resonances with a few coupled two-hadron channels, mostly in the
meson-meson sector. Phase shifts at a few energy values for simple system have
been determined in this first principles approach. Meson-nucleon results are
scarce. The theory for decay channels with more than two hadrons is becoming
ready, the practical applications are progressing. Comparison of lattice results
with model calculations are helpful. I will survey what has been done and how.
