Dark matter production from two evaporating PBH distributions
Arnab Chaudhuri, Baradhwaj Coleppa, Kousik Loho
Particulate Dark Matter (DM), completely isolated from the Standard Model particle sector, can be produced in the early universe from Primordial Black Hole (PBH) evaporation. Howev…
Study of entropy production due to electroweak phase transition in symmetric extension of the Standard Model
Arnab Chaudhuri, Jaydeb Das
In this work we consider the simple symmetric extension to the Standard Model (SM) and proceed to study the nature of electroweak phase transition (EWPT) in the early univers…
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…
Dark matter dilution scenarios in the early universe
Arnab Chaudhuri, Maxim Yu. Khlopov
When the vacuum like energy of the Higgs potential within the standard model undergoes electroweak phase transition, an influx of entropy into the primordial plasma can lead to a s…
Charge asymmetry of new stable quarks in baryon asymmetrical Universe
Arnab Chaudhuri, Maxim Yu. Khlopov
Effects of electroweak phase transition (EWPT) in balance between baryon excess and the excess of stable quarks of new generation is studied. With the conservation of SU(2) symmetr…
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…
Balancing asymmetric dark matter with baryon asymmetry and dilution of frozen dark matter by sphaleron transition
Arnab Chaudhuri, Maxim Yu. Khlopov
In this paper we study the effect of electroweak sphaleron transition or electroweak phase transition (EWPT) in balancing baryon excess to the excess stable quarks of gene…
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…
Entropy production due to electroweak phase transition in the framework of two Higgs doublet model
Arnab Chaudhuri, Maxim Yu. Khlopov
We revisit the possibility of first order electroweak phase transition~(EWPT) in one of the simplest extensions of the Standard Model (SM) scalar sector, namely the two-Higgs-doubl…
PBH evaporation, baryon asymmetry,and dark matter
A. Chaudhuri, A. Dolgov
Sufficiently light primordial black holes (PBH) could evaporate in the very early universe and dilute the preexisting baryon asymmetry and/or the frozen density of stable relics. T…
Dilution of baryon asymmetry in the early universe due to primordial blackhole decay
A. Chaudhuri, A. Dolgov
Primordial black holes which are created at the very early universe can get decayed in the matter dominated era and thus produce photons, hence resulting in dilution of the baryon…
Electroweak phase transition and entropy release in the early universe
Arnab Chaudhuri, Alexander Dolgov
It is shown that the vacuum-like energy of the Higgs potential at non-zero temperatures leads, in the course of the cosmological expansion, to a small but non-negligible rise of th…
