*“A Geometric Approach to the Higgs Branch of 5d SCFTs"*
*
*

_Abstract_

The Higgs Branch of Superconformal Field Theories (SCFT) with 8 
supercharges is a notoriously intricate object to characterize. While 
the magnetic quiver framework has recently provided a powerful indirect 
description - by relating Higgs branches of theories with 8 supercharges 
to the Coulomb branches of auxiliary 3d N=4 theories - a direct 
geometric understanding remains elusive.

In this work we study 5d N=1 SCFTs engineered via M-theory on 
non-compact Calabi-Yau threefolds, where the Higgs branch corresponds to 
the space of normalizable complex structure deformations of the threefold.

Focusing on simple classes of Calabi-Yau threefolds with non-isolated 
singularities, we show how key features of the Higgs branch can be 
captured in a purely geometric fashion, demonstrating precise agreement 
with expectations from brane webs and magnetic quivers. This framework 
might provide new insights on the geometric origin of magnetic quivers.
