Composite solitary waves in three-component scalar field theory: Three-body low-energy scattering

We study the structure of the manifold of solitary waves in a particular three-component scalar field theoretical model in two-dimensional Minkowski space. These solitary waves involve one, two, three, four, six or seven lumps of energy. The adiabatic motion of the non-linear non-dispersive waves composed of three lumps is interpreted as three-body low-energy scattering of these particle-like kinks.
