The baryon asymmetry

- G. White
- Physics
- 2016

This is an in-depth look at baryon number violation in the Standard Model including the necessary background in finite temperature field theory, plasma dynamics and how to calculate the out of… Expand

Testing the Seesaw Mechanism and Leptogenesis with Gravitational Waves.

- J. A. Dror, T. Hiramatsu, K. Kohri, H. Murayama, G. White
- Physics, Medicine
- Physical review letters
- 8 August 2019

We present the possibility that the seesaw mechanism with thermal leptogenesis can be tested using the stochastic gravitational background. Achieving neutrino masses consistent with atmospheric and… Expand

Limits from BBN on light electromagnetic decays

- L. Forestell, D. Morrissey, G. White
- Physics
- 4 September 2018

A bstractInjection of electromagnetic energy — photons, electrons, or positrons — into the plasma of the early universe can destroy light elements created by primordial Big Bang Nucleosynthesis… Expand

Theoretical uncertainties for cosmological first-order phase transitions

- D. Croon, O. Gould, P. Schicho, T. Tenkanen, G. White
- Physics
- 21 September 2020

We critically examine the magnitude of theoretical uncertainties in perturbative calculations of first-order phase transitions, using the Standard Model effective field theory as our guide. In the… Expand

Review of cosmic phase transitions: their significance and experimental signatures.

- A. Mazumdar, G. White
- Physics, Medicine
- Reports on progress in physics. Physical Society
- 5 November 2018

The study of cosmic phase transitions are of central interest in modern cosmology. In the standard model of cosmology the Universe begins in a very hot state, right after at the end of inflation via… Expand

Semi-analytic techniques for calculating bubble wall profiles

- Sujeet Akula, C. Balázs, G. White
- Physics
- 29 July 2016

We present semi-analytic techniques for finding bubble wall profiles during first order phase transitions with multiple scalar fields. Our method involves reducing the problem to an equation with a… Expand

Model discrimination in gravitational wave spectra from dark phase transitions

A bstractIn anticipation of upcoming gravitational wave experiments, we provide a comprehensive overview of the spectra predicted by phase transitions triggered by states from a large variety of dark… Expand

A Pedagogical Introduction to Electroweak Baryogenesis

- G. White
- Physics
- 7 December 2016

This is an in-depth look at baryon number violation in the Standard Model including the necessary background in finite temperature field theory, plasma dynamics and how to calculate the out of… Expand

Gravitational waves from a Pati-Salam phase transition

- D. Croon, T. Gonzalo, G. White
- Physics
- 6 December 2018

A bstractWe analyse the gravitational wave and low energy signatures of a Pati-Salam phase transition. For a Pati-Salam scale of MPS ∼ 105 GeV, we find a stochastic power spectrum within reach of the… Expand
