Duality invariance of all free bosonic and fermionic gauge fields
S. Deser, D. Seminara
TL;DR
This paper extends the concept of duality invariance to all free massless bosonic and fermionic gauge fields, exploring its validity in various backgrounds and the role of supersymmetry.
Contribution
It provides a general proof of duality invariance for all free massless gauge fields, building on recent results for spin 2 and discussing broader implications.
Findings
Duality invariance applies to all free bosonic and fermionic gauge fields.
The invariance holds in flat space and is examined in (A)dS backgrounds.
Supersymmetry's relevance to duality invariance is discussed.
Abstract
We give a simple general extension to all free bosonic and fermionic massless gauge fields of a recent proof that spin 2 is duality invariant in flat space. We also discuss its validity in (A)dS backgrounds and the relevance of supersymmetry.
