Gauge anomalies occur in nearly all Abelian extensions of the Standard Model without additional chiral fermions. The lack of detection of new particles suggests that if a new gauge boson exists, we can integrate out the heavy anomaly-canceling fermions at high scales to obtain a low-energy effective field theory with a non-conserved current. We review the construction of this theory and discuss its phenomenological applications, with a focus on the Wess-Zumino terms describing the effective low energy anomalies. In particular, we show that the requirement of theoretical consistency in dark matter models can lead to enhanced indirect detection signatures.
