Abstract
Three-body physics is important in measuring physical properties of exotic hadrons, which mostly decays into three or more particles under strong interactions. To realize these states using the fundamental theory of strong interactions, Quantum Chromodynamics (QCD), we use a tool called Lattice QCD. LQCD is a systematically improvable numerical technique that solves non-perturbative QCD by putting quarks and gluons on a discretized space-time lattice. Due to the finite volume nature of this method, we can't have asymptotic states, thus no scattering information. But we can map the finite volume results from LQCD to constrain physical dynamical quantities. The path to extracting three-body scattering information is a bit more complicated because on top this mapping, one needs to solve three-body integral equations to get the scattering amplitude. My work focuses on solving the three-body integral equations and extracting dynamical quantities of three-body systems. In this talk, I will present our techniques of studying three-body scattering from Lattice QCD.
