Three-Body Systems from Lattice QCD

Accessing properties of hadrons and nuclei from Quantum ChromoDynamics (QCD) poses several challenges given its non-perturbative nature and the fact that most states couple to multi-particle decay modes. Although challenging, advances in both theoretical and numerical techniques have allowed us to determine few-body systems directly from QCD. A synergistic approach between lattice QCD and scattering theory offers a systematic pathway to numerically compute properties such as the hadron spectrum from first principles. I will present an overview of this program, and discuss developments in determining three-hadron scattering processes using lattice QCD. These techniques allow us to push the boundaries of resolving the few-body problem from first-principles.
