Proton Decay in a 6D SO(10) model
Laura Covi
We present a study of proton decay in a supersymmetric gauge theory in six dimensions compactified on an orbifold. The dimension 5 proton decay operators are absent, but…
Status of observational cosmology and inflation
Laura Covi
We review the latest developments in the determination of the cosmological parameters from the measurement of the Cosmic Microwave Background Radiation (CMBR) anisotropies and of t…
What we can learn on inflation from recent CMBR data
Laura Covi
We review the prediction of inflation and the constraints on inflationary models coming from recent observations.
Models of inflation, supersymmetry breaking and observational constraints
Laura Covi
We review the connection between inflationary models and observations and concentrate to describe models based on softly broken supersymmetry, in particular running mass models, an…
Inflation models, spectral index and observational constraints
Laura Covi
We have evaluated the observational constraints on the spectral index , in the context of a CDM model. For scale-independent, as predicted by most models of inflation, pr…
New developments in inflationary models
Laura Covi
We study models of inflation where the inflaton corresponds to a flat direction in field space and its mass term is generated by gravity mediated soft supersymmetry breaking at hig…
