Post-Inflationary Production of Dark Matter after Inflection Point Slow Roll Inflation
نویسندگان
چکیده
We explore a feasible model that combines near-inflection point small-field slow roll inflationary scenario driven by single scalar inflaton with the production of non-thermal vector-like fermionic dark matter, χ, during reheating era. For scenario, we consider two separate polynomial forms potential; one is symmetric about origin, and other not. fix coefficients potentials satisfying current Planck-Bicep data. calculate permissible range yχ mχ for enough matter to explain total Cold Dark Matter (CDM) mass density present universe while Cosmic Background Radiation (CMBR) measurements cosmological bounds.

Transplanckian energy production and slow roll inflation
In this paper we investigate how the energy density due to a non-standard choice of initial vacuum affects the expansion of the universe during inflation. To do this we introduce source terms in the Friedmann equations making sure that we respect the relation between gravity and thermodynamics. We find that the energy production automatically implies a slow rolling cosmological constant. Hence ...
متن کاملGeneralized slow-roll inflation
The slow-roll approximation to inflation is ultimately justified by the presence of inflationary attractors for the orbits of the solutions of the dynamical equations in phase space. There are many indications that the inflaton field couples nonminimally to the spacetime curvature: the existence of attractor points for inflation with nonminimal coupling is demonstrated, subject to a condition o...
متن کاملInflection-point Higgs Inflation
Inflection-point inflation is an interesting possibility to realize a successful slow-roll inflation when inflation is driven by a single scalar field with its initial value below the Planck mass (φI . MP l). In order for a renormalization group (RG) improved effective λφ4 potential to develop an inflection-point, the quartic coupling λ(φ) must exhibit a minimum with an almost vanishing value i...
متن کاملInflation without slow roll
We draw attention to the possibility that inflation (i.e. accelerated expansion) might continue after the end of slow roll, during a period of fast oscillations of the inflaton field φ. This phenomenon takes place when a mild non-convexity inequality is satisfied by the potential V (φ). The presence of such a period of φ-oscillation-driven inflation can substantially modify reheating scenarios....
متن کاملBrane inflation without slow-roll
The scenario of brane inflation without using the conventional slow-roll approximations has been investigated. Based on the mechanism of generating the curvature perturbations at the end of inflation, a new brane inflation paradigm was developed. The conditions for making a sufficiently large enough number of e-foldings and for generating the curvature perturbations without producing dangerous ...
