Lattice QCD has seen great success in computing ground-state quantities, and several groups have shown that energy levels describing excited hadrons can be extracted. Extending a theoretical framework originally derived by Lüscher, these energy levels have been shown to map out the infinite-volume scattering amplitudes to compare to experiment. In recent years, we have seen rapid progress in the applications of these techniques to resonant scattering processes including meson-meson, meson-baryon and baryon-baryon interactions. Future applications of these methods, at higher energies and lighter pion masses, require an extension of the formalism to three-body scattering channels. Significant steps in this direction have been made. However practical applications are still in their infancy.
This workshop will combine introductory lectures and progress reports on recent developments by lattice practitioners working on problems with relevance for phenomenology. The idea of the volume dependence of the energy spectrum has recently been successfully applied to the scattering of the worldsheet theory of flux tube dynamics at low energies. One of the invited speakers will discuss the bridge between the lattice scattering techniques and the theory of relativistic strings with integrable dynamics on the worldsheet.
