Effective Theory of Large-Scale Structure with Primordial Non-Gaussianity
Valentin Assassi, Daniel Baumann, Enrico Pajer +2
We develop the effective theory of large-scale structure for non-Gaussian initial conditions. The effective stress tensor in the dark matter equations of motion contains new operat…
On the viability of m**2 phi**2 and natural inflation
Ana Achucarro, Vicente Atal, Yvette Welling
In the context of single field inflation, models with a quadratic potential and models with a natural potential with subplanckian decay constant are in tension with the Planck data…
Multiple Field Inflation and Signatures of Heavy Physics in the CMB
Ana Achúcarro, Yvette Welling
In this master thesis we study multi-field inflation and the UV sensitivity of certain models of inflation in supergravity. We first introduce inflation and its current observation…
