Description
The reconciliation of observable properties of hadrons with the fundamentals of QCD has remained a persisting challenge in modern nuclear theory. Lattice QCD is a numerical method that bridges the gap between first-principles QCD and observables in nuclear systems in the strong coupling regime. By casting a scattering problem onto a finite, discretized spacetime lattice, one obtains a finite-volume energy spectrum that corresponds directly to an infinite volume scattering amplitude. Much progress has been made in calculations of meson-meson interactions from Lattice QCD by the hadron spectroscopy community, but the baryon sector has seen little exploration. Because of the significant contribution of three-body effects, baryon-meson and baryon-baryon calculations are ideal for developing the finite-volume formalism to accommodate the analysis of three-body scattering processes. We present an overview of a lattice calculation of a baryon-meson scattering amplitude.
