ADE Spectral Networks and Decoupling Limits of Surface Defects
Pietro Longhi, Chan Y. Park
We study vacua and BPS spectra of canonical surface defects of class theories in different decoupling limits using ADE spectral networks. In some regions of the IR mo…
Wall-Crossing Invariants from Spectral Networks
Pietro Longhi
A new construction of BPS monodromies for 4d theories of class S is introduced. A novel feature of this construction is its manifest invariance under Kontsevich-So…
The Vector-like Twin Higgs
Nathaniel Craig, Simon Knapen, Pietro Longhi +1
We present a version of the twin Higgs mechanism with vector-like top partners. In this setup all gauge anomalies automatically cancel, even without twin leptons. The matter conten…
ADE Spectral Networks
Pietro Longhi, Chan Y. Park
We introduce a new perspective and a generalization of spectral networks for 4d theories of class associated to Lie algebras $\mathfrak{g} = \textrm{A…
