Three-body resonances in the φ 4 theory

Three-body resonances in the φ 4 theory

Abstract We study the properties of three-body resonances using a lattice complex scalar φ 4 theory with two scalars, with parameters chosen such that one heavy particle can decay into three light ones. We determine the two- and three-body spectra for several lattice volumes using variational techni...
