TL;DR: In this paper, the authors examine the magnitude of theoretical uncertainties in perturbative calculations of fist-order phase transitions, using the Standard Model effective field theory as their guide, and find large uncertainties due to renormalization scale dependence, which amount to two to three orders of magnitude uncertainty in the peak gravitational wave amplitude, relevant to experiments such as LISA.

TL;DR: In this paper, the authors examine the magnitude of theoretical uncertainties in perturbative calculations of first-order phase transitions, using the Standard Model effective field theory as their guide, and find large uncertainties due to renormalization scale dependence, which amount to two to three orders of magnitude uncertainty in the peak gravitational wave amplitude, relevant to experiments such as LISA.

TL;DR: In this article, the authors present the first end-to-end nonperturbative analysis of the gravitational wave power spectrum from a thermal first-order electroweak phase transition.

TL;DR: In this article, the authors revisited the perturbative expansion at high temperature and investigated its convergence by inspecting the renormalisation scale dependence of the effective potential, showing that at zero temperature, the improved effective potential is scale independent at one-loop, due to the misalignment of loop and coupling expansions.

TL;DR: In this paper, the rate of thermal Schwinger pair production at arbitrary coupling in weak external fields was calculated independently of many properties of the charged particles produced, in particular their spin and whether they are electric or magnetic.
