Numerical study of multiparticle production in $\lambda {\varphi }^4$ theory

S. Demidov, B. Farkhtdinov, D. Levkov

We study multiparticle production in the unbroken $(3+1)$-dimensional $\lambda {\varphi }^4$ theory using the semiclassical method of singular solutions. We show that the probabilities of these pr…
