Unified Model for Inflation and the Dark Side of the Universe

چکیده
We present a model with a complex and a real scalar fields and a potential whose symmetry is explicitly broken by Planck-scale physics. For exponentially small breaking, the model accounts for the period of inflation in the early universe and for the period of acceleration of the late universe or for the dark matter, depending on the smallness of the explicit breaking.

Unified Model for Inflation and Dark Matter
Abstract 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 relating inflation with the dark matter of the universe. We find that for exponentially small explicit breaking, the model accounts for a perio...
متن کاملA meshless discrete Galerkin method for solving the universe evolution differential equations based on the moving least squares approximation
In terms of observational data, there are some problems in the standard Big Bang cosmological model. Inflation era, early accelerated phase of the evolution of the universe, can successfully solve these problems. The inflation epoch can be explained by scalar inflaton field. The evolution of this field is presented by a non-linear differential equation. This equation is considered in FLRW model...
متن کاملVery Light Gravitino Dark Matter * * *
It is certainly very attractive that two longstanding open questions -the origin of electroweak symmetry breaking -and the nature of the non-baryonic dark matter in the Universeseem to be on the verge of being answered simultaneously and presumably in a unified framework. LHC will give us the opportunity to start scratching the surface of this issue and, if we are lucky enough, to hint more cle...
متن کاملUnified model for inflation and dark energy
We present a model based on the idea that Planck-scale effects may produce a small explicit breaking of global symmetries. The model contains a new complex scalar field Ψ, charged under a certain global U(1) symmetry, interacting with a new real scalar field χ, neutral under U(1). For exponentially small breaking, the model accounts for both early and late periods of acceleration of the univers...
متن کاملFormation of Large Structures in the Acceleration Universe with a Hybrid Expansion Law
In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...
