42. Gravitational waves from phase transitions at the electroweak scale

Prof. Mark Hindmarsh (Sussex)

11/4/20, 4:00 PM

In extensions of the Standard Model of particle physics, this could have been a first order phase transition, at about 10 picoseconds after the Big Bang. I will discuss the dynamics of the transition, the characteristic spectrum of gravitational radiation, and the prospects for observing the radiation at the future space-based gravitational wave detector LISA.

43. Gravitational waves from first-order phase transitions: Towards a better prediction

Dr Ryusuke Jinno (DESY)

11/4/20, 5:00 PM

In the upcoming decades, gravitational waves (GWs) will be an important tool in probing the early Universe and in testing high energy physics. In this lecture I will review GW production in cosmological first-order phase transitions, putting more emphasis on analytic understanding of the process. The structure of the lecture will be:
- Basics of GW production in the early Universe
- GW...
