Abstrakt: We study multiparticle production in the unbroken -dimensional theory using semiclassical method of singular solutions. We show that the probabilities of these processes are exponentially suppressed in terms of a small coupling constant if the multiplicity of the final state is large: . At the probabilities agree with the well–known perturbative results. At they are dominated by loop effects and decrease exponentially with , as we show for the first time. [ABSTRACT FROM AUTHOR]
