Post-inflationary Leptogenesis and Dark Matter production: Metric versus Palatini formalism
Anish Ghoshal, Zygmunt Lalak, Supratik Pal +1
We investigate production of non-thermal dark matter particles and heavy sterile neutrinos from inflaton during the reheating era, which is preceded by a slow-roll inflationary epo…
Post-inflationary production of particle Dark Matter: Hilltop and Coleman-Weinberg inflation
Anish Ghoshal, Maxim Yu. Khlopov, Zygmunt Lalak +1
We investigate the production of non-thermal dark matter (DM), , during post-inflationary reheating era. For inflation, we consider two slow roll single field inflationary scena…
Post-inflationary production of particle Dark Matter: non-minimal Natural and Coleman--Weinberg inflationary scenarios
Anish Ghoshal, Maxim Yu. Khlopov, Zygmunt Lalak +1
We investigate the production of non-thermal fermionic dark matter particles during the reheating era following slow roll inflation, driven by inflaton non-minimally coupled to…
Proceedings to the 25th International Workshop "What Comes Beyond the Standard Models", July 4 -- July 10, 2022, Bled, Slovenia
R. Bernabei, P. Belli, A. Bussolotti +51
Proceedings for our meeting ``What comes beyond the Standard Models'', which covered a broad series of subjects.
Measuring inflaton couplings via dark radiation as in CMB
Anish Ghoshal, Zygmunt Lalak, Shiladitya Porey
We study the production of a beyond the Standard Model (BSM) free-streaming relativistic particles which contribute to and investigate how much the predictions for the in…
Near-inflection point inflation and production of dark matter during reheating
Anish Ghoshal, Gaetano Lambiase, Supratik Pal +2
We study slow roll single field inflationary scenario and the production of non-thermal fermionic dark matter, together with standard model Higgs, during reheating. For the inflati…
Inflection-point Inflation and Dark Matter Redux
Anish Ghoshal, Gaetano Lambiase, Supratik Pal +2
We investigate for viable models of inflation that can successfully produce dark matter (DM) from inflaton decay process, satisfying all the constraints from Cosmic Microwave Backg…
Entopy release in Electroweak Phase Transition in 2HDM
Arnab Chaudhuri, Maxim Yu. Khlopov, Shiladitya Porey
Electroweak phase transition in the simplest extension of the standard model namely two Higgs doublet model and entropy production within this framework is studied. We have conside…
Particle dark matter density and entropy production in the early universe
Arnab Chaudhuri, Maxim Yu. Khlopov, Shiladitya Porey
Dark Matter (DM) density is reduced if entropy production takes place after DM particles abundance is frozen out in the early universe. We study a possibility of such reduction due…
Effects of 2HDM in electroweak phase transition
Arnab Chaudhuri, Maxim Yu. Khlopov, Shiladitya Porey
The entropy production scenarios due to electroweak phase transition (EWPT) in the framework of the minimal extension of standard model namely two Higgs doublet model(2HDM) is revi…
On mass distribution of coalescing black holes
A. D. Dolgov, A. G. Kuranov, N. A. Mitichkin +4
Available data on the chirp mass distribution of the coalescing black hole binaries in O1-O3 LIGO/Virgo runs are analyzed and compared statistically with the distribution calculate…
Massive primordial black holes in contemporary universe
A. D. Dolgov, S. Porey
The parameters of the original log-normal mass spectrum of primordial black holes (PBH) are approximately adjusted on the basis of existing observational data on supermassive black…
Formation and evaporation of an electrically charged black hole in conformal gravity
Cosimo Bambi, Leonardo Modesto, Shiladitya Porey +1
Extending previous work on the formation and the evaporation of black holes in conformal gravity, in the present paper we study the gravitational collapse of a spherically symmetri…
Black hole evaporation in conformal gravity
Cosimo Bambi, Leonardo Modesto, Shiladitya Porey +1
We study the formation and the evaporation of a spherically symmetric black hole in conformal gravity. From the collapse of a spherically symmetric thin shell of radiation, we find…
