It is argued that the amplitudes of the production of n soft scalar particles by one or a few energetic ones in theories like λϕ^4 has the exponential form, A_n∝√(n!)[1λF(λ n,ϵ)], in the regime λ→ 0, λ n=fixed, ϵ=fixed, where ϵ is the typical kinetic energy of outgoing particles. Existing results support this conjecture. Several new analytical and numerical results in favor of the exponential behavior of multiparticle amplitudes are presented.doi:10.1103/physrevd.50.7553 pmid:10017739 fatcat:r3el445znrdtxdkdg6qghvgpwa
