Massless Wigner particles in conformal field theory are free
Published online by Cambridge University Press: 22 August 2014
Abstract
We show that the massless particle spectrum in a four-dimensional conformal Haag–Kastler net is generated by a free field subnet. If the massless particle spectrum is scalar, then the free field subnet decouples as a tensor product component.
