The electroweak phase transition (EWPT) is a key event that took place
early in the evolution of the Universe. Knowledge of its precise details could help us
understand the origin of the baryon asymmetry, or may lead to a definite prediction of a
stochastic background of gravitational waves that may be within the reach of the future
space-based interferometer LISA. At the same time, exploring the nature and properties
of the EWPT is an increasingly important part of the Physics Programme of the LHC
and the future of the high-energy frontier, and a large effort has been devoted in recent
years to the exploration of the phenomenological consequences of the EWPT for LHC.

Translating the future experimental results into a precise description of the early
Universe during the electroweak epoch demands a robust computational framework for
scenarios beyond the Standard Model, and is not yet fully established. The aim of this
Workshop is to bring together experts in the field to discuss the latest theoretical
developments, share ideas, and bring the EWPT into the precision era.

Workshop Goals & Key Themes:

-Theory aspects of perturbative approaches to the EWPT: How can we get more
accurate/reliable answers in a tractable way for BSM scenarios? Critical Bubble &
Tunneling; Resummation Techniques; Gauge Invariance.
-B+L Violating solutions in the early Universe: Beyond the Standard Model.
-Non-perturbative Methods & Lattice: Beyond the Standard Model.
-Gravitational Wave spectrum from the EWPT.
