DESCRIPTION:Speakers: Tuomas Tenkanen\n\nMotivated by their prospects to p
 roduce potentially observable primordial gravitational wave background\, a
 s well as to provide a viable mechanism for baryogenesis\, understanding t
 he physics of Electroweak phase transitions has been a hot topic for a lon
 g time. In this talk\, I will present developments from the past decade th
 at have culminated in: i) automating the required dimensionally reduced\, 
 thermal effective field theory (EFT) descriptions\; ii) gaining an intuiti
 ve understanding of the underlying 'supersoft' mass scale above the non-pe
 rturbative scale of confinement for scalar field-driven phase transitions\
 ; iii) including thermal loop corrections up to and including three loops\
 ; and iv) building effective perturbative descriptions for bubble nucleati
 on and sphaleron rates in the thermal plasma. Finally\, I will envision fu
 ture directions for studying Beyond the Standard Model theories at high te
 mperatures\, and high-loop-order perturbative calculations beyond simple E
 FTs built upon high-temperature expansions.\n\nhttps://indico.cern.ch/even
