Abstract
Positive energy ray representations of the Poincare group are naturally subdivided into three classes according to their mass and spin content: m>0, m=0 finite helicity and m=0 infinite spin. Whereas the intrinsic noncompact localization accounts for its inertness, the possible existence of finite spin s ≥ 2 inert matter is less clear.
