Gravitational waves from dark SU(3) Yang-Mills theory

We analyze the phase transition in improved holographic QCD to obtain an estimate of the gravitational wave signal emitted in the confinement transition of a pure SU(3) Yang-Mills dark sector. We derive the effective action from holography and show that the energy budget and duration of the phase transition can be calculated with minor errors. These are used as input to obtain a prediction of the gravitational wave signal. To our knowledge, this is the first computation of the gravitational wave signal in a holographic model designated to match lattice data on the thermal properties of pure Yang-Mills.

Automated summary

We estimate the gravitational wave signal emitted in the confinement transition of a pure SU(3) Yang-Mills dark sector by analyzing the phase transition in improved holographic QCD. We calculate the energy budget and duration of the phase transition with minor errors using the derived effective action from holography. These calculations are then used to predict the gravitational wave signal. This is the first computation of gravitational wave signal in a holographic model designed to match lattice data on the thermal properties of pure Yang-Mills.
