The Standard Model of Particle Physics as a Conspiracy Theory and the Possible Role of the Higgs Boson in the Evolution of the Early Universe [PDF]

open access: diamondActa Physica Polonica B, 2021
I am considering Veltman's 'The Infrared - Ultraviolet Connection' addressing the issue of quadratic divergences and the related huge radiative correction predicted by the electroweak Standard Model (SM) in the relationship between the bare and the renormalized theory, commonly called 'the hierarchy problem' which usually is claimed that this has to be

Possible Relics from New Physics in the Early Universe: Inflation, the Cosmic Microwave Background, and Particle Dark Matter [PDF]

open access: green, 1998
I review two different connections between particle theory and early-Universe cosmology: (1) Cosmic-microwave-background (CMB) tests of inflation and (2) particle dark matter. The inflationary predictions of a flat Universe and a nearly scale-invariant spectrum of primordial density perturbations will be tested precisely with forthcoming maps of the ...

The Early Universe and the Standard Model of Particle Physics [PDF]

open access: green, 2001
The most well tested and successful model of particle physics is the Standard Model (SM). It is shown here that the restoration of the full SM symmetry (as in the Early Universe) leads to the result that the electric charge loses all physical meaning and hence does not exist above this scale, As a direct consequence of this we show that `time', `light'

Non-linear scalar field dynamics in particle physics motivated models of the early universe [PDF]

open access: green, 2018
In particle physics motivated models of the early universe, non-linear preheating dynamics of scalar fields can give rise to rich phenomenology. An example phenomenon is e.g. the formation of oscillons: quasi-stable, localised, and non-linear scalar field configurations.

Phase transitions and the birth of early universe particle physics

open access: hybridStudies in History and Philosophy of Science
This paper provides a conceptual history of the development of early universe particle physics in the 1970s, focusing on the development of more sophisticated tools for constructing gauge-theories at finite-temperature. I start with a focus on early investigations into spontaneous symmetry restoration, and continue through the development of functional

Precision early universe cosmology from stochastic gravitational waves

open access: yesJournal of High Energy Physics, 2022
The causal tail of stochastic gravitational waves can be used to probe the energy density in free streaming relativistic species as well as measure g * (T) and beta functions β(T) as a function of temperature.
