Numerical study of multiparticle production in $\lambda\phi^4$ theory

Autor: Demidov, S., Farkhtdinov, B., Levkov, D.

Publikováno v: Phys. Part. Nuclei Lett. 20, 229-232 (2023)

We study multiparticle production in the unbroken $(3+1)$-dimensional $\lambda\phi^4$ theory using the semiclassical method of singular solutions. We show that the probabilities of these processes are exponentially suppressed in terms of a small coup

Autor: Demidov, S. V., Farkhtdinov, B. R., Levkov, D. G.

Publikováno v: J. High Energ. Phys. 2023, 205 (2023)

We compute the probability of producing $n$ particles from few colliding particles in the unbroken $(3+1)$-dimensional $\lambda\phi^4$ theory. To this end we numerically implement semiclassical method of singular solutions which works at ${n \gg 1}$

Numerical study of multiparticle production in $\phi^4$ theory: comparison with analytic results

Autor: Demidov, S. V., Farkhtdinov, B. R., Levkov, D. G.

Publikováno v: Jetp Lett. 114 (2021) 649 [Pisma Zh.Eksp.Teor.Fiz. 114 (2021) 723]

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 $1 \to n$ in the unb

Numerical study of multiparticle scattering in $\lambda\phi^4$ theory

Autor: Demidov, S. V., Farkhtdinov, B. R.

We study numerically classical collisions of waves in $\lambda\phi^4$ theory. These processes correspond to multiparticle scattering in the semiclassical regime. Parametrizing initial and final wavepackets by energy $E$ and particle numbers $N_{i}$,
