Shift Symmetries in (Anti) de Sitter Space
James Bonifacio, Kurt Hinterbichler, Austin Joyce +1
We construct a class of extended shift symmetries for fields of all integer spins in de Sitter (dS) and anti-de Sitter (AdS) space. These generalize the shift symmetry, galileon sy…
Shapes of gravity: Tensor non-Gaussianity and massive spin-2 fields
Garrett Goon, Kurt Hinterbichler, Austin Joyce +1
If the graviton is the only high spin particle present during inflation, then the form of the observable tensor three-point function is fixed by de Sitter symmetry at leading order…
Inflationary soft theorems revisited: A generalized consistency relation
Lam Hui, Austin Joyce, Sam S. C. Wong
We reconsider the derivation of soft theorems associated with nonlinearly-realized symmetries in cosmology. Utilizing the path integral, we derive a generalized consistency relatio…
