 Haag–Łopuszański–Sohnius theorem

The Haag–Łopuszański–Sohnius theorem is a result in theoretical physics concerning the structure of supersymmetry. Specifically, it states conditions under which a globally supersymmetric field theory can exist. The theorem is one of the foundational results in the study of supersymmetry, which is a symmetry relating bosons (particles with integer spin) and fermions (particles with half-integer spin).
