Non-Abelian currents bootstrap

We initiate the study of correlation functions of non-Abelian spin-1 conserved current in three dimensional conformal field theories using numerical conformal bootstrap. We discuss the general framework and apply it to the particular cases of $SU(N)$ and $O(N)$ global symmetry. In both cases we obtain general bounds on operator dimensions. In the large-$N$ limit our bounds show features in correspondence of the expected position of fermionic QED${}_3$ in three dimensions, as well as other interesting theories. By imposing gaps inspired by the spectrum of QED${}_3$ at large-$N$, we manage to restrict the plane of certain operator dimensions to a small island, where QED${}_3$ must live.
