Magnetic quivers for rank 2 theories

International audienceA bstract In this note we construct magnetic quivers for the known rank-2 four dimensional $$ \mathcal{N} $$ N = 2 superconformal field theories. For every rank-1 theory one can find a unitary magnetic quiver; we observe that this is no longer possible at rank 2. Our list of magnetic quivers necessarily includes orthosymplectic quivers, in addition to unitary ones, of both the simply and non simply laced variety. Using quiver subtraction, one can compute Higgs branch Hasse diagrams and compare with the results obtained via other methods finding nearly perfect agreement
