What the heck happens when the Universe boils?

A cosmological first order phase transition is one of the murkiest areas of fun-
damental 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 unfavourable 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 prediction 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 schedules with lots of time for discussion.
