Description
5d SCFTs can be constructed in String theory via two main approaches. 1) Geometric engineering in M-theory on local Calabi-Yau threefolds (CY3s). 2) As a worldvolume theory on five-brane webs ending on seven-branes in Type IIB String Theory. The possible Higgsings of 5d SCFTs are well understood in the second construction, using branes and so called magnetic quivers. From the geometry side, however, they are much less understood. For 5d SCFTs where both constructions are available, we will show how specific deformations of the CY3 map to turning on moduli for specific branes in the brane web, thus exploring every symplectic leaf in the Higgs branch of the 5d SCFT. This provides a step in understanding the Higgs branch of a 5d SCFT from a purely geometric perspective.
