# Asymptotic completeness for infraparticles in two-dimensional conformal field theory

December 18, 2011

We formulate a new concept of asymptotic completeness for two-dimensional
massless quantum field theories in the spirit of the theory of particle
weights. We show that this concept is more general than the standard particle
interpretation based on Buchholz' scattering theory of waves. In particular, it
holds in any chiral conformal field theory in an irreducible product
representation and in any completely rational conformal field theory. This
class contains theories of infraparticles to which the scattering theory of
waves does not apply.
