Relativistic invariance and charge conjugation in quantum field theory
It is proved that superselection sectors with finite statistics in the sense of Doplicher, Haag and Roberts are automatically Poincaré covariant. Main tools are the Bisognano-Wichmann description of the modular structure of the von Neumann algebras and the relation between Jones index theory for subfactors and the statistics of superselection sectors.
