Anomalies of Discrete 1-Form Symmetries in QCD-like Theories
Abstract: In this talk we will discuss a new class of non-perturbative anomalies of discrete 1-form global symmetries in 4D QCD-like theories. This generalizes the techniques developed by Wang-Wen-Witten to more general theories that allow for discrete 1-form global symmetries including chiral gauge theories. We will demonstrate several new anomalies and comment on their implication on symmetric mass generation in 3+1D.
