Snowmass White Paper: The Cosmological Bootstrap
Daniel Baumann, Daniel Green, Austin Joyce +4
This white paper summarizes recent progress in the cosmological bootstrap, an approach to the study of the statistics of primordial fluctuations from consistency with unitarity, lo…
Snowmass White Paper: Cosmology at the Theory Frontier
Raphael Flauger, Victor Gorbenko, Austin Joyce +3
The precision cosmological model describing the origin and expansion history of the universe, with observed structure seeded at the inflationary cosmic horizon, demands completion…
Matter Couplings and Equivalence Principles for Soft Scalars
James Bonifacio, Kurt Hinterbichler, Laura A. Johnson +2
Scalar effective field theories with enhanced soft limits behave in many ways like gauge theories and gravity. In particular, symmetries fix the structure of interactions and the t…
The Cosmological Bootstrap: Weight-Shifting Operators and Scalar Seeds
Daniel Baumann, Carlos Duaso Pueyo, Austin Joyce +2
A key insight of the bootstrap approach to cosmological correlations is the fact that all correlators of slow-roll inflation can be reduced to a unique building block---the four-po…
Shift-Symmetric Spin-1 Theories
James Bonifacio, Kurt Hinterbichler, Laura A. Johnson +1
We study interacting massive spin-1 theories in de Sitter (dS) and anti-de Sitter (AdS) space that possess shift symmetries parametrized by (A)dS Killing vectors. We show how they…
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…
