Description
To gain general principles of QCD from the spectrum and structure of hadrons, it is necessary to look across a broad range of states and see if patterns emerge. This is no small task due to two major obstacles. First, of course QCD is non-perturbative, which can in-principle be overcome with the use of lattice QCD. Second, the vast majority of states are unstable resonances that decay rapidly to multi-hadron states, and their existence can only be deduce from the dynamical properties of the scattering amplitudes of their byproducts. This has motivated an increasingly sophisticated program to study resonant scattering processes via lattice QCD. In this talk, I will review this rich ongoing program, and discuss how this may be one-day be used to access structural information of even resonant states.
