Description
We report on the gravitational wave spectrum study from the confinement transition in the one-flavor SU(4) Hyper Stealth Dark Matter theory. We use the multihistogram method to construct the Polyakov loop effective potential in the complex plane, from which the order of transition as well as the tunneling rate is obtained. This method allows us to study the gravitational wave spectrum down to the second-order point, where the sea-quark effect becomes relevant. The decrease in the surface tension due to the sea quarks leads to a decrease in the amplitude of the gravitational waves.
