 There are no interacting [[tag:superconformal|superconformal field theories]] in $d>6$ because there are no superconformal algebras (satisfying certain assumptions). This follows from the classification of superconformal algebras due to [[https://inspirehep.net/literature/120988|Nahm]]. See also the proof of [[https://arxiv.org/abs/hep-th/9712074|Minwalla]] for a more recent discussion. There are no interacting [[tag:superconformal|superconformal field theories]] in $d>6$ because there are no superconformal algebras (satisfying certain assumptions).

 +These apparently exist, even nonperturbatively. What's the conformal symmetry group? Possibly relevant: [[http://mr.crossref.org/iPage?doi=10.1070%2FRM1988v043n02ABEH001720]]

 +Here's an example of the Ising model on the Sierpinski carpet: [[https://arxiv.org/abs/cond-mat/9802018]].
