# Infraparticles with superselected direction of motion in two-dimensional conformal field theory

January 29, 2011

Particle aspects of two-dimensional conformal field theories are
investigated, using methods from algebraic quantum field theory. The results
include asymptotic completeness in terms of (counterparts of) Wigner particles
in any vacuum representation and the existence of (counterparts of)
infraparticles in any charged irreducible product representation of a given
chiral conformal field theory. Moreover, an interesting interplay between
infraparticle's direction of motion and the superselection structure is
demonstrated in a large class of examples. This phenomenon resembles electron's
momentum superselection expected in quantum electrodynamics.
