We study the inter-particle potentials for few-particle systems in a scalartheory with a non-linear mediating field of the Higgs type. We use thevariational method, in a reformulated Hamiltonian formalism of QFT, to deriverelativistic three and four particle wave equations for stationary states ofthese systems. We show that the cubic and quartic non-linear terms modify theattractive Yukawa potentials but do not change the attractive nature of theinteraction if the mediating fields are massive.
