Bootstrapping Multi-Field Inflation: non-Gaussianities from light scalars revisited
Dong-Gang Wang, Guilherme L. Pimentel, Ana Achúcarro
Primordial non-Gaussianities from multi-field inflation are a leading target for cosmological observations, because of the possible large correlations generated between long and sh…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
Boostless Cosmological Collider Bootstrap
Guilherme L. Pimentel, Dong-Gang Wang
Cosmological correlation functions contain valuable information about the primordial Universe, with possible signatures of new massive particles at very high energies. Recent devel…
Inflation: Theory and Observations
Ana Achúcarro, Matteo Biagetti, Matteo Braglia +19
Cosmic inflation provides a window to the highest energy densities accessible in nature, far beyond those achievable in any realistic terrestrial experiment. Theoretical insights i…
Linking the Singularities of Cosmological Correlators
Daniel Baumann, Wei-Ming Chen, Carlos Duaso Pueyo +3
Much of the structure of cosmological correlators is controlled by their singularities, which in turn are fixed in terms of flat-space scattering amplitudes. An important challenge…
Fundamental limits on constraining primordial non-Gaussianity
Alba Kalaja, P. Daniel Meerburg, Guilherme L. Pimentel +1
We study the cosmic variance limit on constraining primordial non-Gaussianity for a variety of theory-motivated shapes. We consider general arguments for 2D and 3D surveys, with a…
