Particle states transforming in one of the infinite spin representations of the Poincaré group (as classified by E. Wigner) are consistent with fundamental physical principles, but local fields generating them from the vacuum state cannot exist. While it is known that infinite spin states localized in a spacelike cone are dense in the one-particle space, we show here that the subspace of states localized in any double cone is trivial. This implies that the free field theory associated with… Expand
Wigner’s infinite spin representations and inert matter
Positive energy ray representations of the Poincaré group are naturally subdivided into three classes according to their mass and spin content: $$m > 0, m=0$$m>0,m=0 finite helicity and $$m=0$$m=0Expand
Split property for free massless finite helicity fields
We prove the split property for any finite helicity free quantum fields. Finite helicity Poincar\'e representations extend to the conformal group and the conformal covariance plays an essential roleExpand
The enigma of dark matter and its possible connection with Wigner's infinite spin representations
Positive energy ray representations of the Poincar\'e group are naturally subdivided into three classes according to their mass and spin content: m>0, m=0 finite helicity and m=0 infinite helicity.Expand
Helicity decoupling in the massless limit of massive tensor fields
Massive and massless potentials play an essential role in the perturbative formulation of particle interactions. Many difficulties arise due to the indefinite metric in gauge theoretic approaches, orExpand
The role of positivity and causality in interactions involving higher spin
It is shown that the recently introduced positivity and causality preserving string-local quantum field theory (SLFT) resolves most No-Go situations in higher spin problems. This includes inExpand
