Hybrid α-attractors, primordial black holes and gravitational wave backgrounds

چکیده
We investigate the two-stage inflation regime in theory of hybrid cosmological $\alpha$-attractors. The spectrum inflationary perturbations is compatible with latest Planck/BICEP/Keck results, thanks to attractor properties model. However, at smaller scales, it may have a very high peak controllable width and position, leading copious production primordial black holes (PBH) generation stochastic background gravitational waves (SGWB).

Massive Primordial Black Holes in Hybrid Inflation
It is well known that energy density fluctuations at the early Universe give rise primordial black holes (BH) formation [1]. Widespread opinion is that these BHs are small enough with masses somewhere in the range MBH ∼ 10−5 − 10gram depending on specific model. What could be said about BHs with masses in the range 10 − 10gram? There exist a few number of inflationary models that predict BH pro...
متن کاملHybrid Inflation without Flat Directions and without Primordial Black Holes
We investigate the possibility that the Universe may inflate due to moduli fields, corresponding to flat directions of supersymmetry, lifted by supergravity corrections. Using a hybrid-type potential we obtain a two-stage inflationary model. Depending on the curvature of the potential the first stage corresponds to a period of fast-roll inflation or a period of ‘locked’ inflation, induced by an...
متن کاملFormation and Evolution of Primordial Black Holes After Hybrid Inflation
We examine the formation and evolution of primordial black holes (PBH’s) after hybrid inflation. Our goal is to assess the effects of various theoretical uncertainties on the extrapolation from a given inflation model to a spectrum of primordial black hole masses. The context of our work is an examination of the possibility[1, 2] that the dark matter is comprised of Planck-mass black hole remna...
متن کاملPrimordial Black Holes
Primordial black holes (PBHs) are a profound signature of primordial cosmological structures and provide a theoretical tool to study nontrivial physics of the early Universe. The mechanisms of PBH formation are discussed and observational constraints on the PBH spectrum, or effects of PBH evaporation, are shown to restrict a wide range of particle physics models, predicting an enhancement of th...
متن کاملCosmological Gravitational Wave Backgrounds
An overview is presented of possible cosmologically distant sources of gravitational wave backgrounds, especially those which might produce detectable backgrounds in the LISA band between 0.1 and 100 mHz. Examples considered here include inflation-amplified vacuum fluctuations in inflaton and graviton fields, bubble collisions in first-order phase transitions, Goldstone modes of classical self-...
