Description
With the approval of the space-based LISA experiment, the hunt is on: A search for gravitational-wave remnants of the Electroweak phase transition; to probe the Higgs potential and perchance even explain the Baryon asymmetry problem. Yet the theoretical hurdles are great—theoretical predictions can misjudge the peak gravitational-wave spectrum by orders of magnitude.
In this talk I will illustrate the progress of using perturbation theory, together with Lattice Monte-Carlo simulations, to give robust predictions of the gravitational-wave spectrum from phase transitions. To that end I will compare state-of-the-art theoretical calculations with new Lattice simulations and discuss how remaining theoretical hurdles can be overcome.
