Abstract
We develop a numerical method to compute the probabilities of multiparticle production in weakly coupled scalar theories. Our technique is based on D.T. Son's semiclassical method of singular solutions. Applying it to the process in the unbroken four-dimensional theory, we reproduce the known results at .
