Anomalies of 4d Theories
T. Daniel Brennan, Kenneth Intriligator
We consider 't Hooft anomalies of four-dimensional gauge theories whose fermion matter content admits generalized spin structure, with either gauged or a global sym…

Anomaly Enforced Gaplessness for Background Flux Anomalies and Symmetry Fractionalization
T. Daniel Brennan, Aiden Sheckler
Anomalous symmetries are known to strongly constrain the possible IR behavior along any renormalization group (RG) flow. Recently, the extension of the notion of symmetry in QFT ha…
