Anomalies for anomalous symmetries
Avner Karasik
4d gauge theories with massless fermions typically have axial U(1) transformations that suffer from the ABJ anomaly. One can modify the theory of interest by adding more fields in…

On Discrete Anomalies in Chiral Gauge Theories
Philip Boyle Smith, Avner Karasik, Nakarin Lohitsiri +1
We study two well-known chiral gauge theories with fermions in the symmetric, anti-symmetric and fundamental representations. We give a detailed description of the global s…
