Unified Model for Inflation and Dark Matter
We present a model which contains a new complex scalar field Ψ, interacting with a new real scalar field, χ, and an effective potential whose symmetry is almost exact, being explicitly broken by Planck-scale effects. We study the possibility of relatin g inflation with the dark matter of the univers...

| Sumario: | We present a model which contains a new complex scalar field Ψ, interacting with a new real scalar field, χ, and an effective potential whose symmetry is almost exact, being explicitly broken by Planck-scale effects. We study the possibility of relatin g inflation with the dark matter of the universe. We find that for exponentially small explicit breaking, the model accounts for a period of inflation in the early universe and gives a dark matter candidate particle. |
