Description
Accessing the hadron spectrum 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-body scattering processes and electroweak transitions of multi-hadron systems. These techniques allow us to push the boundaries of resolving the few-body problem in spectroscopy, and gives us insight into the structure of hadrons as the emergent phenomena of QCD.
