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 ...

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

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.

Large primordial fluctuations in gravitational waves from phase transitions
Journal of High Energy Physics, 2023 It is well-known that first-order phase transitions in the early universe can be a powerful source of observable stochastic gravitational wave backgrounds.

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

Journal of High Energy Physics, 2023 In this work, we assess the sensitivity reach of pulsar timing array (PTA) measurements to probe pointlike primordial black holes (PBHs), with an extended mass distribution, which originate from collapsed Fermi balls that are formed through the ...

The supercooling window at weak and strong coupling
Journal of High Energy Physics, 2023 Supercooled first order phase transitions are typical of theories where conformal symmetry is predominantly spontaneously broken. In these theories the fate of the flat scalar direction is highly sensitive to the size and the scaling dimension of the ...

宇宙早期双通道真空框架下量子阱的稳态场模型A Steady-State Field Model for Quantum Wells in a Dual-Channel Vacuum Framework at the Early Universe At the beginning of the universe, the physical processes of matter formation and development involve annihilation reaction pairs within particles. This paper assumes that in the early quantum spacetime, there were sufficient
