Anomalies on ALE spaces and phases of gauge theory
Mohamed M. Anber
We show that certain 't Hooft anomalies not detected by standard closed four-dimensional probes can become visible when a quantum field theory is placed on asymptotically locally E…
-duality, boundary states, and higher-form symmetries on ALE spaces
Mohamed M. Anber
We study Abelian -duality of Maxwell theory on -type asymptotically locally Euclidean (ALE) spaces. Unlike on closed four-manifolds, the Maxwell path integral on an ALE space…
Gauging the Standard Model 1-form symmetry via gravitational instantons
Mohamed M. Anber
We investigate the fate of the Standard Model (SM) electric -form global symmetry in the background of gravitational instantons, focusing on Eguchi-Hanson (E…
On the moduli space of multi-fractional instantons on the twisted
Mohamed M. Anber, Andrew A. Cox, Erich Poppitz
The moduli space of self-dual Yang-Mills instantons on of topological charge , , is of current interest, yet is not fully understo…
Mass-deformed Super Yang-Mills theory on : sum over twisted sectors, -angle, and CP violation
Mohamed M. Anber, Erich Poppitz
We study super Yang-Mills theory with a small gaugino mass and vacuum angle on the four-torus with 't Hooft twisted boundary conditions. Introducing…
Higher-order gaugino condensates on a twisted : In the beginning was semi-classics
Mohamed M. Anber, Erich Poppitz
We compute the gaugino condensates, for , in super Yang-Mills theory on a small f…
