Cosmological consequences of Particle Physics models

Objective

The main objective of this proposal is to better understand the interplay between cosmological data and the particle physics models underlying it. Cosmological data give strong support for inflation, and a well-motivated particle physics model leading to inflation is being sought.

A promising connection between cosmology and high-energy physics comes from extended objects. For a number of years there has been considerable interest in the cosmological impact of topological defects from super-symmetric theories, which can exhibit interesting new properties with respect to their non-super-symmetric counterparts. More recently, interest was further stimulated by the realization that the soliton solutions in four-dimensional super-gravity may be directly identified with ten-dimensional super-string states whose low energy limit they represent.

These super-gravity defects typically would have a potentially measurable effect on the Cosmic Microwave Background Radiation. Therefore, comparison with cosmological data might provide some information about the compactification parameters of super-string theory. That will be our aim: consider the extended objects appearing in different high energy physics models, study their cosmological implications, and use them as feed-back to constrain the initial model.
