Abstract

We solve the classical euclidean boundary value problem for tree-level multiparticle production in ϕ4\phi^4 theory at arbitrary energies in the case of O(4)O(4) symmetric field configurations. We reproduce known low-energy results and obtain a lower bound on the tree cross sections at arbitrary energies.
