Comment on "Anomaly Mediation from Unbroken Supergravity"

TL;DR

This paper critiques a previous work by clarifying misconceptions about Weyl transformations in supergravity, emphasizing the importance of correct symmetry identification in theoretical physics.

Contribution

It clarifies the role of Weyl transformations in supergravity, correcting a misunderstanding in a prior publication.

Findings

Weyl transformations are not true symmetries in the discussed context

Misinterpretation affects the understanding of anomaly mediation

Clarification impacts supergravity model building

Abstract

I argue that ArXiv:1307.3251 is based on a misunderstanding of the role of Weyl transformations in local off-shell supersymmetry and what constitutes a true symmetry of the theory.
