Scattering processes and resonances from lattice QCD

Abstract

Hadrons and their interactions arise via the coupling between quarks and gluons, as dictated by quantum chromodynamics (QCD), the theory of strong interactions. Unlike protons and neutrons, very few hadrons observed in nature are stable under the strong interaction: the majority of them appear as resonances in scattering experiments. This work reviews progress and prospects in the studies of few-hadron reactions and resonance properties using lattice QCD techniques.
