DESCRIPTION:The three-body problem\, renowned for its unsolvable nature in
  celestial mechanics and homonymous science fiction\, is not only solvable
  in the quantum realm regarding spectra but also offers profound insights 
 into QCD. In this talk\, I will present the first-ever lattice calculation
  of the resonance parameters for the lightest hadron decaying into three p
 articles\, the ω-meson. By mapping finite-volume energy levels to infinit
 e-volume scattering amplitude\, a pole position trajectory is obtained tha
 t\, when extrapolated to the physical point\, shows good agreement with th
 e experiment.\n\nhttps://indico.hiskp.uni-bonn.de/event/815/
