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