Primordial Black Hole Production in Natural and Hilltop Inflation
Jessica L. Cook
We consider the possibility of primordial black hole, PBH, formation sourced by a rise in the power spectrum. The power spectrum becomes large at late times due to decay of the inf…
Low Scale Inflation at High Energy Colliders and Meson Factories
Joseph Bramante, Jessica Cook, Antonio Delgado +1
Inflation occurring at energy densities less than (10 GeV) produces tensor perturbations too small to be measured by cosmological surveys. However, we show that it is po…
Large Slow Roll Parameters in Single Field Inflation
Jessica L. Cook, Lawrence M. Krauss
We initially consider two simple situations where inflationary slow roll parameters are large and modes no longer freeze out shortly after exiting the horizon, treating both cases…
Reheating predictions in single field inflation
Jessica L. Cook, Emanuela Dimastrogiovanni, Damien A. Easson +1
Reheating is a transition era after the end of inflation, during which the inflaton is converted into the particles that populate the Universe at later times. No direct cosmologica…
Is Higgs Inflation Dead?
Jessica L. Cook, Lawrence M. Krauss, Andrew J. Long +1
We consider the status of Higgs Inflation in light of the recently announced detection of B-modes in the polarization of the cosmic microwave background radiation by the BICEP2 col…
An inflationary model with small scalar and large tensor nongaussianities
Jessica L. Cook, Lorenzo Sorbo
We study a model of inflation where the scalar perturbations are almost gaussian while there is sizable (equilateral) nongaussianity in the tensor sector. In this model, a rolling…
