Abstract: In exploring supersymmetric theories with 8 supercharges, the Higgs branches present an intriguing window into strong coupling dynamics. Magnetic quivers serve as crucial tools for understanding these branches. I will introduce a new algorithm for magnetic quivers called Decay and Fission which reflects the possible Higgs branch RG-flows (Higgsings) of the supersymmetric theory. I will apply them to various theories in dimensions 3,4,5,6 including 4d class S theories, Argyres-Douglas theories, 5d SQCD theories at UV fixed point, 6d (1,0) SCFTs, Little String Theories and more. On the geometry side, the algorithm also efficiently generates the complete Higgs branch phase diagram (Hasse diagram) and hints to the existence of a new minimal transition (isolated symplectic singularity).
