The Massive Flat Space Limit of Cosmological Correlators
Sebastian Cespedes, Sadra Jazayeri
Identifying useful flat-space limits for cosmological correlators, where they can be expressed in terms of observables in Minkowski space is nontrivial due to their scale-invariant…
Every Wrinkle Carries A Memory: An Integro-differential Bootstrap for Features in Cosmological Correlators
Sadra Jazayeri, Xi Tong, Yuhang Zhu
Motivated by cosmological observations, we push the cosmological bootstrap program beyond the de Sitter invariance lamppost by considering correlators that explicitly break scale i…
Cosmological Correlator Discontinuities from Scattering Amplitudes
Chandramouli Chowdhury, Sadra Jazayeri, Arthur Lipstein +3
Recent theoretical work has revealed that basic observables of quantum field theory in de Sitter space, known as in-in or cosmological correlators, exhibit surprisingly simple math…
Bispectrum Islands
Claudia de Rham, Sadra Jazayeri, Andrew J. Tolley
Inspired by the amplitude bootstrap program, the spirit of this work is to constrain the space of consistent inflationary correlation functions - specifically, the bispectrum of cu…
Cosmological Bootstrap in Slow Motion
Sadra Jazayeri, Sébastien Renaux-Petel
Speed matters. How the masses and spins of new particles active during inflation can be read off from the statistical properties of primordial density fluctuations is well understo…
