We examine observational constraints on chaotic inflation models in the Randall-Sundrum type II braneworld. If inflation takes place in the high-energy regime, the perturbations produced by the quadratic potential are further from scale invariance than in the standard cosmology, in the quartic case more or less unchanged, while for potentials of greater exponent the trend is reversed. We test these predictions against a data compilation including the Wilkinson Microwave Anisotropy Probe… Expand

Constraints on braneworld inflation from CMB anisotropies
We obtain observational constraints on Randall–Sundrum type II braneworld inflation using a compilation of data including WMAP, the 2dF and latest SDSS galaxy redshift surveys. We place constraintsExpand
Strong Planck constraints on braneworld and non-commutative inflation
We place observational likelihood constraints on braneworld and non-commutative inflation for a number of inflaton potentials, using Planck, WMAP polarization and BAO data. Both braneworld andExpand
Natural braneworld inflation and baryogenesis
Abstract In natural inflation models, the inflaton is a pseudo Nambu–Goldstone boson and the flatness of the potential is protected by shift symmetries. In this framework, a successful inflationExpand
Primordial perturbations from slow-roll inflation on a brane
In this paper we quantize scalar perturbations in a Randall–Sundrum-type model of inflation where the inflaton field is confined to a single brane embedded in five-dimensional anti-de SitterExpand
Degeneracy of consistency equations in braneworld inflation
In a Randall–Sundrum type II inflationary scenario we compute perturbation amplitudes and spectral indices up to next-to-lowest order in the slow-roll parameters, starting from the well-knownExpand
Sneutrino brane inflation and leptogenesis
Modifications to the Friedmann equation in brane cosmology can have important implications for early universe phenomena such as inflation and the generation of the baryon asymmetry. We study a simpleExpand
Braneworld inflation from an effective field theory after WMAP three-year data
In light of the results from the WMAP three-year sky survey, we study an inflationary model based on a single-field polynomial potential, with up to quartic terms in the inflaton field. Our analysisExpand
We study a new inflation potential in the framework of the Randall–Sundrum type II braneworld model. Using the technic developed in Ref. 1, we consider both a monomial and a new inflation potentialsExpand
Observational constraints on reheating in braneworld inflation
The reheating era after inflation is analyzed in the framework of the braneworld models. We study reheating by calculating the reheating temperature in a braneworld inflation for various cosmologicalExpand
Topics in stringy cosmology
This thesis is composed of two distinct research topics. The first topic concerns RandallSundrum cosmological models, in particular their isotropization properties at early times. We first study theExpand
