Abstract

We study numerically classical collisions of waves in λϕ4\lambda\phi^4 theory. These processes correspond to multiparticle scattering in the semiclassical regime. Parametrizing initial and final wavepackets by energy EE and particle numbers NiN_{i}, NfN_{f} we find classically allowed region in the parameter space. We describe properties of the scattering solutions at the boundary of the classically allowed region. We comment on the implications of our results for multiparticle production in the quantum regime.
