Antonella Cid, Sergio del Campo
TL;DR
This paper investigates an intermediate inflation model within Jordan-Brans-Dicke theory, analyzing quantum fluctuations and comparing results with Einstein gravity, to evaluate compatibility with WMAP data.
Contribution
It introduces an intermediate inflationary scenario in Jordan-Brans-Dicke theory and compares its predictions to Einstein gravity models using observational data.
Findings
Quantum fluctuations analyzed for adiabatic and isocurvature modes
Model assessed against seven-year WMAP data
Comparison shows compatibility with observational constraints
Abstract
We study an intermediate inflationary stage in a Jordan-Brans-Dicke theory. In this scenario we analyze the quantum fluctuations corresponding to adiabatic and isocurvature modes. Our model is compared to that described by using the intermediate model in Einstein general relativity theory. We assess the status of this model in light of the seven-year WMAP data.
