CMSA Quantum Matter in Mathematics and Physics: Instantons, symmetries and anomalies in five dimensions
CMSA EVENTS
Speaker:
Luigi Tizzano - SCGP
All five-dimensional non-abelian gauge theories have a U(1) global symmetry associated with instantonic particles. I will describe a mixed ’t Hooft anomaly between this and other global symmetries such as the one-form center symmetry or the ordinary flavor symmetry for theories with fundamental matter. I will also discuss how these results can be applied to supersymmetric gauge theories in five dimensions, analyzing the symmetry enhancement patterns occurring at their conjectured RG fixed points.
