String Consistency, Heavy Exotics, and the GeV Diphoton Excess at the LHC
Mirjam Cvetič, James Halverson, Paul Langacker
String consistency conditions are stronger than anomaly cancellation and can require the addition of exotics in the visible sector. We study such exotics and demonstrate that they…

-bundle bases and the prevalence of non-Higgsable structure in 4D F-theory models
James Halverson, Washington Taylor
We explore a large class of F-theory compactifications to four dimensions. We find evidence that gauge groups that cannot be Higgsed without breaking supersymmetry, often accompani…

On Gauge Enhancement and Singular Limits in Compactifications of M-theory
James Halverson, David R. Morrison
We study the physics of singular limits of compactifications of M-theory, which are necessary to obtain a compactification with non-abelian gauge symmetry or massless charged…
