From pq-webs to magnetic quivers and back II: distributional indices and 5d theories breaking bad
Abstract
This is the second of two companion papers in which we study five-dimensional 𝒩=1 theories engineered by (p,q) five-brane webs and their associated three-dimensional magnetic quivers. Leveraging the exact parameter dictionary between the N+SU(N)0k−1+N theories and their magnetic quivers at infinite coupling, proposed in the first paper, we investigate nilpotent moment-map VEV deformations and their three-dimensional counterparts. We show that, when the Higgsing is excessive, the five-dimensional superconformal index becomes distributional, mirroring a characteristic feature of bad and broken theories in three dimensions. We also develop a five-brane web interpretation of these results, identifying the Hanany-Witten moves associated with the Higgsing cascade and relating inequivalent frames to distinct tessellations of the generalised toric diagram.
