Abstract
A method for reducing the problem of calculating multiparticle tree cr oss sections in phi(4) theory to the solution of a singular classical Euclidean boundary-value problem is introduced. The solutions are obta ined numerically in terms of the spherical harmonic decomposition, and the corresponding estimates of the tree cross sections are found at a rbitrary energies. Numerical analysis agrees with analytic results obt ained earlier in the limiting cases of high and low energies.
