PBH formation in EFT of single field inflation with sharp transition

نویسندگان

چکیده

Using the Effective Field Theory (EFT) framework of single field inflation, we investigate possibility formation Primordial Black Holes (PBHs) in Slow Roll (SR) to Ultra (USR) sharp transition. We demonstrate that, due one-loop correction power spectrum, causality is violated (cs>1) for mass range PBHs, MPBH>102gm created during said find that non-canonical features with cs<1 worsen predictions canonical single-field inflation.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Tachyon inflation : tests and comparison with single scalar field inflation

We compare the standard single scalar field inflationary predictions with those of an inflationary phase driven by a tachyon field. A slow-roll formalism is defined for tachyon inflation, and we derive the spectra of scalar and tensor perturbations as well as the consistency relations. At lowest order the predictions of standard and tachyon inflation are shown to be the same. Higher order devia...

Asymmetric Behavior of Inflation in Iran: New Evidence on Inflation Persistence Using a Smooth Transition Model

T his paper investigates the asymmetric behavior of inflation. We use logistic smooth transition autoregressive (LSTAR) model to characterize the regime-switching behavior of Iran’s monthly inflation during the period May 1990 to December 2013. We find that there is a triple relationship between the inflation level, its fluctuations and persistence. The findings imply that the behavi...

Trispectrum versus bispectrum in single-field inflation

In the standard slow-roll inflationary cosmology, quantum fluctuations in a single field, the inflaton, generate approximately Gaussian primordial density perturbations. At present, the bispectrum and trispectrum of the density perturbations have not been observed and the probability distribution for these perturbations is consistent with Gaussianity. However, Planck satellite data will bring a...

Large Non-Gaussianities in Single Field Inflation

We compute the 3-point correlation function for a general model of inflation driven by a single, minimally coupled scalar field. Our approach is based on the numerical evaluation of both the perturbation equations and the integrals which contribute to the 3-point function. Consequently, we can analyze models where the potential has a “feature”, in the vicinity of which the slow roll parameters ...
