Scale-invariance, dynamically induced Planck scale and inflation in the Palatini formulation

چکیده
Abstract We present two scale invariant models of inflation in which the addition quadratic curvature terms usual Einstein-Hilbert action, context Palatini formulation gravity, manages to reduce value tensor-to-scalar ratio. In both Planck is dynamically generated via vacuum expectation scalar fields.

The effective Planck mass and the scale of inflation
Observable quantities in cosmology are dimensionless, and therefore independent of the units in which they are measured. This is true of all physical quantities associated with the primordial perturbations that source cosmic microwave background anisotropies such as their amplitude and spectral properties. However, if one were to try and infer an absolute energy scale for inflation-a priori, on...
متن کاملFalse Vacuum Inflation Beyond the Planck Scale in Supergravity
We present a false vacuum inflationary scenario in which the inflaton field takes values considerably larger than the Planck scale. It is based on a class of inflationary potentials which can be derived from singular Kähler potentials in supergravity. Our scenario allows for a detectable gravitational wave contribution to the microwave background anisotropy.
متن کاملEffective Planck mass and the scale of inflation
A recent paper argued that it is not possible to infer the energy scale of inflation from the amplitude of tensor fluctuations in the Cosmic Microwave Background, because the usual connection is substantially altered if there are a large number of universally coupled fields present during inflation, with mass less than the inflationary Hubble scale. We give a simple argument demonstrating that ...
متن کاملInflation From Symmetry Breaking Below the Planck Scale
We investigate general scalar field potentials V (φ) for inflationary cosmology arising from spontaneous symmetry breaking. We find that potentials which are dominated by terms of order φm with m > 2 can satisfy observational constraints at an arbitrary symmetry breaking scale. Of particular interest, the spectral index of density fluctuations is shown to be independent of the specific form of ...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
