Three-body bound states in finite volume with effective field theory — •Simon Kreuzer and Hans-Werner Hammer — Helmholtz-Institut für Strahlen- und Kernphysik (Theorie), Universität Bonn
In lattice simulations, a good understanding of the finite-volume dependence of the calculated observables is required to establish a quantitative connection to experiment. We investigate the volume dependence of the three-body system using an Effective Field Theory for short-range forces. We develop an expansion of the 3-body bound state amplitude in partial waves and show first results for the shift in the binding energy.
