Dear all,

We are happy to announce that the hybrid workshop "What the heck happens when the Universe boils?" is held on the following schedule:

Date: December 5-9, 2022.
Venue: Kavli IPMU (https://www.ipmu.jp/en) and Zoom (Hybrid style)
Website: https://indico.ipmu.jp/event/414/overview

The purpose of the workshop is as follows:

A cosmological first-order phase transition is one of the murkiest areas of fundamental physics. However, if such a phase transition occurred, it could explain why we are here and leave startling gravitational wave signals. Further, multi-billion-dollar machines are expected to shed light on the nature of cosmological electroweak symmetry breaking in the next few decades: from next-generation particle colliders to gravitational wave detectors to searches for permanent electric dipole moments. Unless conditions turn out to be very unfavorable either for a first-order transition or electroweak baryogenesis, it will be virtually impossible to make robust statements about the viability of different models without substantial progress in understanding the underlying theory.

The challenges facing our community are fourfold,
1 How to make robust predictions of charge asymmetries produced by CP-violating interactions with a bubble wall? Current methods disagree by many orders of magnitude.
2 How useful is perturbation theory in predicting the nature of a phase transition? If it is useful, how do we organize perturbation theory?
3 Can we make sense of bubble wall velocities in the ultra-relativistic and sub-relativistic regimes?
4 How well can we predict the gravitational wave spectra from macroscopic physics?

In this workshop, we will bring together young researchers who are leaders in each of these areas to present their latest findings and discuss how to overcome these challenges. This workshop will have a light schedule with lots of time for discussion.

Currently confirmed invited speakers:

Yikun Wang (Caltech)
Jorinde Van De Vis (Utrecht/Desy)
Bjorn Garbrecht (Technical University of Munich)
Tuomas Tenkanen (Nordita and TD Lee, Shanghai)
Jyotirmoy Roy (University of Toronto

We are looking forward to seeing many of you.
Please also feel free to share the information with your colleagues.
