Phase transitions and the birth of early universe particle physics
Studies in History and Philosophy of Science Part AThis 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

Quantum scale of inflation and particle physics of the early universe [PDF]
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1994 The quantum gravitational scale of inflation is calculated by finding a sharp probability peak in the distribution function of chaotic inflationary cosmologies driven by a scalar field with large negative constant $ξ$ of nonminimal interaction. In the case of the no-boundary state of the universe this peak corresponds to the eternal inflation, while ...

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]
Acta 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

Two or three things particle physicists (mis)understand about (pre)heating [PDF]
Nuclear Physics BThe transition from the end of inflation to a hot, thermal Universe, commonly referred to as (re)heating, is a critical yet often misunderstood phase in early Universe cosmology.

Cosmological phase transitions: From perturbative particle physics to gravitational waves [PDF]
Progress in Particle and Nuclear Physics, 2023 Gravitational waves (GWs) were recently detected for the first time. This revolutionary discovery opens a new way of learning about particle physics through GWs from first-order phase transitions (FOPTs) in the early Universe.

Probing early Universe supercooled phase transitions with gravitational wave data [PDF]
Physical Review D, 2022 We investigate the reach of the LIGO/Virgo/KAGRA detectors in the search for signatures of first-order phase transitions in the early Universe. Utilising data from the first three observing runs, we derive constraints on the parameters of the underlying ...

Dark matter and the early Universe: A review [PDF]
, 2021 Dark matter represents currently an outstanding problem in both cosmology and particle physics. In this review we discuss the possible explanations for dark matter and the experimental observables which can eventually lead to the discovery of dark matter

Precision early universe cosmology from stochastic gravitational waves
Journal 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.
