We clarify inflaton models by considering them as effective field theories in the Ginzburg-Landau spirit. In this new approach, the precise form of the inflationary potential is constructed from the present WMAP data, and a useful scheme is prepared to confront with the forthcoming data. In this approach, the WMAP statement excluding the pure {phi}{sup 4} potential implies the presence of an inflaton mass term at the scale m{approx}10{sup 13} GeV. Chaotic, new and hybrid inflation models are…

Clarifying Inflation Models: Slow-roll as an expansion in 1/N_{efolds}
Slow-roll inflation is studied as an effective field theory. We find that the form of the inflaton potential consistent with Wilkinson Microwave Anisotropy Probe (WMAP) data and slow roll is
Inflation is part of the Standard Model of the Universe supported by CMB and large scale structure LSS datasets. This review presents new developments of inflation in three main chapters. (I): The
Predictions of single field inflation for the tensor/scalar ratio and the running spectral index
We study the single field slow-roll inflation models that better agree with the available CMB and LSS data including the three years WMAP data: new inflation and hybrid inflation. We study these
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 analysis
Monte Carlo Markov chains analysis of WMAP3 and SDSS data points to broken symmetry inflaton potentials and provides a lower bound on the tensor to scalar ratio

New inflation vs. chaotic inflation, higher degree potentials and the reconstruction program in light of WMAP3
The cosmic microwave background power spectra are studied for different families of single field new and chaotic inflation models in the effective field theory approach to inflation. We implement a
Cmb quadrupole suppression. I. Initial conditions of inflationary perturbations
We investigate the issue of initial conditions of curvature and tensor perturbations at the beginning of slow roll inflation and their effect on the power spectra. Renormalizability and small

Within the effective field theory of inflation, an initialization of the classical dynamics of the inflaton with approximate equipartition between the kinetic and potential energy of the inflaton


Uncertainties in coupling constant unification.
A simple parametrization of a general supersymmetric new particle spectrum is given and it is shown that an effective scale can be defined, but for a realistic spectrum it may differ considerably from the typical new particle masses.
Reheat temperature in supersymmetric hybrid inflation models
The allowed range of parameters for supersymmetric hybrid inflation and its extensions are investigated. The lower bound on the reheat temperature ${T}_{r}$ in these models with hierarchical
False vacuum inflation with Einstein gravity.
Investigation of chaotic inflation models with two scalar fields, such that one field (the inflaton) rolls while the other is trapped in a false vacuum state, finds that false vacuum inflation occurs with the inflaton field far below the Planck scale, making it easier to implement in the context of supergravity than standard chaotic inflation.
Inflationary universe: A possible solution to the horizon and flatness problems
The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: (1) The early universe is assumed to be highly homogeneous, in spite of the fact that
Nonperturbative quantum dynamics of a new inflation model
We consider an O(N) model coupled self-consistently to gravity in the semiclassical approximation, where the field is subject to {open_quotes}new inflation{close_quotes} type initial conditions. We
Large scale structure and supersymmetric inflation without fine tuning.
This work presents a new class of inflationary models based on realistic supersymmetric grand unified theories which do not have the usual `fine tuning' problems and is found to be proportional to the GUT (Planck) scale.
Quantum inflaton, primordial perturbations, and CMB fluctuations
We compute the primordial scalar, vector and tensor metric perturbations arising from quantum field inflation. Quantum field inflation takes into account the nonperturbative quantum dynamics of the
