Let $M(p,q)$ denote the minimal model, and consider its $(1,7)$ perturbation. Let … with spin … The search found a conserved current of spin $20$ when $p=9$. This conjecture concer…

Let ${\cal M}_4$ be the four-dimensional Siegel space, let $M^4\subset{\cal M}_4$ be its Minkowski-space submanifold, and let $Q_4$ denote the charge defined on ${\cal M}_4$. In Mi…
