The $\mathcal {OSP}(2,2|16)$ superconformal theory is free! [PDF]
Dmitry Belyaev, Patrick Hearin, Pierre RamondThe SuperConformal theory in three space-time dimensions with SO(16) $R$-symmetry, 128 bosons, and 128 fermions, cannot sustain interactions. This result is obtained using both light-cone superspace techniques which rely on algebraic consistency, and covariant methods which rely on SO(16) Fierz identities which fail to produce the desired algebra.View original: http://arxiv.org/abs/1208.1699
