The graviton four-point function in de Sitter space
James Bonifacio, Harry Goodhew, Austin Joyce +2
We compute the tree-level late-time graviton four-point correlation function, and the related quartic wavefunction coefficient, for Einstein gravity in de Sitter spacetime. We deri…
Parity violation in the scalar trispectrum: no-go theorems and yes-go examples
Giovanni Cabass, Sadra Jazayeri, Enrico Pajer +1
We derive a set of no-go theorems and yes-go examples for the parity-odd primordial trispectrum of curvature perturbations. We work at tree-level in the decoupling limit of the Eff…
On Graviton non-Gaussianities in the Effective Field Theory of Inflation
Giovanni Cabass, David Stefanyszyn, Jakub Supeł +1
We derive parity-even graviton bispectra in the Effective Field Theory of Inflation (EFToI) to all orders in derivatives. Working in perturbation theory, we construct all cubic int…
