Description

In this talk, we will discuss the testability of a scale invariant extension of the standard model with a QCD-like hidden sector by using the gravitational wave (GW) signal. The scale invariance is dynamically broken by the non-perturbative effects, which can be used to explain the origin of masses of the Higgs boson and the dark matter. In a certain region of the parameter space, the chiral phase transition in the QCD-like hidden sector is of first order. We will estimate the GW signal from the phase transition and show the parameter points which predict a sizable GW signal by future space based detectors.
