Description
Strongly-coupled dark sectors offer natural UV-complete extensions to the Standard Model that are challenging to access experimentally if they are only weakly coupled to the Standard Model. In this talk, I will present the possibility to test these dark sectors via gravitational-wave signals from the dark confinement phase transition. Due to the non-perturbative nature of the QCD-like sectors, we adapt Lattice data to effective Polyakov-loop models from which we can compute the bubble nucleation in the early Universe and eventually the statistical gravitational-wave signal. I will present results for general SU(N) Yang-Mills sectors allowing a birds-eye view on the dependence on the number of dark colours.
The talk is based on: "Testing the dark SU(N) Yang-Mills theory confined landscape: From the lattice to gravitational waves" (https://arxiv.org/abs/2012.11614)
