Signatures of bulk neutrinos in the early Universe [PDF]

Physical Review D
Neutrino masses and quantum gravity are strong reasons to extend the standard model of particle physics. A large extra dimension can be motivated by quantum gravity and can explain the small neutrino masses with new singlet states that propagate in the ...

Elementary particles and the early Universe:A synergy of particle physics and cosmology in the birth and evolution of the Universe

, 2022
The birth of the Universe, and its subsequent evolution, is an exciting blend of Cosmology, Particle Physics and Thermodynamics. This book, with its synoptic approach, provides an accessible introduction to these fascinating topics.

Emergent Gauge Symmetries in Particle Physics and Cosmology [PDF]

Acta Physica Polonica B
Where do gauge symmetries come from? This article develops the idea that the Standard Model might be emergent, with its gauge symmetries dissolving in some phase transition deep in the ultraviolet.

Chemical evolution of antimatter domains in early Universe [PDF]

According to modern physics, our Universe is baryon-asymmetric. That phenomenon can not be described in the frameworks of the Standard Model of particle physics. Globally, the Universe consists of baryon matter.

F(R) gravity in the early Universe: electroweak phase transition and chameleon mechanism [PDF]

Chinese Physics C, High Energy Physics & Nuclear Physics, 2018
It is widely believed that the screening mechanism is an essential feature for the modified gravity theory. Although this mechanism has been examined thoroughly in the past decade, their analyses are based on a conventional fluid prescription for the ...

REVIEW OF PARTICLE PHYSICS Particle Data Group [PDF]

, 2018
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,873 new measurements from 758 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson ...

Cold Particle Dark Matter [PDF]

, 2021
Possible dark matter candidates in particle physics span a mass range extending over fifty orders of magnitude. In this review, we consider the range of masses from a few keV to a few hundred TeV, which is relevant for cold particle dark matter.

Scalar induced resonant sterile neutrino production in the early Universe [PDF]

, 2019
It has been recently suggested \cite{Bezrukov:2017ike,Bezrukov:2018wvd} that a cosmic scalar field can completely change the keV-scale sterile neutrino production in the early Universe.

Cosmological Phase Transitions: From Particle Physics to Gravitational Waves, Semi-Analytically [PDF]

Highlights in High-Energy Physics
Motivated by the recent evidence of a stochastic gravitational wave background found by pulsar timing array experiments, we focus on one of the prime cosmological explanations, i.e., a supercooled first order phase transition.
