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.

Probing primordial black holes from a first order phase transition through pulsar timing and gravitational wave signals

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 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

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 ...

Phase Transitions in the Universe [PDF]

, 1998
During the past two decades, cosmologists turned to particle physics in order to explore the physics of the very early Universe. The main link between the physics of the smallest and largest structures in the Universe is the idea of spontaneous symmetry ...

Doubly peaked induced stochastic gravitational wave background: testing baryogenesis from primordial black holes

Journal of High Energy Physics, 2022
Hawking evaporation of primordial black holes (PBHs) can facilitate the generation of matter-antimatter asymmetry. We focus on ultra-low mass PBHs that briefly dominate the universe and evaporate before the big bang nucleosynthesis.

Topological Defects and Cosmology [PDF]

, 1998
Many particle physics models of matter admit solutions corresponding to stable or long-lived topological defects. In the context of standard cosmology it is then unavoidable that such defects will form during phase transitions in the very early Universe.
