't Hooft anomalies have long been used in the study of quantum gauge theories because of the nonperturbative constraints they impose on low energy physics. Recently, new 't Hooft anomalies were discovered involving discrete symmetries acting on non-local operators. Such anomalies mean new constraints, which suggest interesting topological structures for low energy theories. In this talk, I explore an example of these new anomalies in a 4d toy model by explicitly calculating the matching in the low energy theory. The talk is based on the recently published paper, https://doi.org/10.1007/JHEP01(2021)091 (https://arxiv.org/abs/2009.14667).
