Multiparticle amplitudes in a scalar EFT
Abstract At sufficiently high energies the production of a very large number of particles is kinematically allowed. However, it is well-known that already in the simplest case of a weakly-coupled massive λφ 4 theory, n-particle amplitudes become non-perturbative in the limit where n scales with ener...
