Non-gaussianity from the inflationary trispectrum
David Seery, James E. Lidsey
We present an estimate for the non-linear parameter τ_NL, which measures the non-gaussianity imprinted in the trispectrum of the comoving curvature perturbation, ζ. Our estimate is…
Primordial Non-Gaussianity and Gravitational Waves: Observational Tests of Brane Inflation in String Theory
James E. Lidsey, David Seery
We study brane inflation scenarios in a warped throat geometry and show that there exists a consistency condition between the non-Gaussianity of the curvature perturbation and the…
Classicality of the primordial perturbations
David H. Lyth, David Seery
We show that during inflation, a quantum fluctuation becomes classical at all orders if it becomes classical at first order. Implications are discussed.
Non-Gaussian Inflationary Perturbations from the dS/CFT Correspondence
David Seery, James E. Lidsey
We use the dS/CFT correspondence and bulk gravity to predict the form of the renormalized holographic three-point correlation function of the operator which is dual to the inflaton…
