Abstract

A construction of massive free fields with arbitrary spin and reversed spin-statistics re- lation is presented. The main idea of the construction is to consider fields that transform according to representations of the Lorentz group that are doubled in comparison with the representations according to which normal (physical) fields transform. This allows the defini- tion of opposite commutation properties for these fields, while the spin of the particles they describe remains unchanged. The correspondence established by the construction between fields obeying normal and reversed spin-statistics relation makes it possible to express e.g. the polarization states, (anti)commutators, or Feynman propagators of the latter fields in terms of those of the normal fields to which they correspond. The cases of the scalar and Dirac fields are discussed in additional detai.
