Description

Hadron scattering information can be accessed indirectly from lattice QCD by computing the spectrum of multi-hadron states and connecting to the infinite volume amplitudes via quantization conditions. This methodology was applied successfully for the two-hadron case to extract phase-shifts and resonance parameters. Only recently this methodology was extended to the three-hadron sector: both lattice QCD calculations and developing quantization conditions is more challenging in this sector. I review our results for two and three meson scattering and their connection with infinite volume amplitudes.
