Trace anomalies for Weyl fermions: too odd to be true?

Trace anomalies for Weyl fermions: too odd to be true?

Abdallah, S.; Franchino-Vinas, S.; Frob, M. B.

We review recent discussions regarding the parity-odd contribution to the trace anomaly of a chiral fermion. We pay special attention to the perturbative approach in terms of Feynman diagrams, comparing in detail the results obtained using dimensional regularization and the Breitenlohner–Maison prescription with other approaches.

Keywords: Trace anomaly; Weyl fermions; Pontryagin density; Parity-odd contribution
