Session:
Phase Transitions
Phase transitions can have a dramatic impact on physics in the early universe. We illustrate this by discussing novel mechanisms of dark matter production, baryogenesis and primordial black hole production which hinge on cosmological phase transitions.

Session:
Phase Transitions
In this talk, we will discuss a novel source of gravitational waves from first order phase transitions beyond the ones conventionally studied in the literature (scalar field and sound waves): feebly interacting particles. If such particles carry a significant fraction of the energy released in the transition, they can generate gravitational wave signals that have qualitatively distinct characteris

Session:
Phase Transitions
We demonstrate analytically and numerically that "optimized partial dressing" (OPD) thermal mass resummation, which uses gap equation solutions inserted into the tadpole, efficiently tames finite temperature perturbation theory calculations of the effective thermal potential, without necessitating use of the high-temperature approximation. An analytical estimate of the scale dependence for OPD res

Session:
Phase Transitions
Gravitational waves are an important probe of physics beyond the Standard Model, especially in theories with a first order phase transitions in the early universe. I will review aspects of simulations and models of the generation of gravitational radiation, calculations of phase transition parameters, and prospects for their estimation at the future space-based gravitational wave detector LISA.

Session:
Phase Transitions
When the universe was a fraction of nano-second old the electroweak phase transition (EWPT) took place in which elementary particles obtained masses via the Higgs mechanism. In extensions of the Standard Model this transition can be first order with possibly observable consequences. It would be great to have a simple and model-independent description of this process in terms of the Standard Model
