Abstract
AbstractWe consider a particle dark matter model by extending the Standard Model (SM) of particle physics by an extra Higgs doublet and a real singlet scalar. The added Higgs doublet is attributed to be an inert doublet and the lightest inert particle acts as a viable candidate of dark matter. We consider a finite temperature effective potential to explore the first-order phase transition (FOPT) within the framework of the model. We also discuss the possible production mechanisms of gravitational waves (GWs) from the strong FOPT. Finally, we calculate the intensities and frequencies of such GWs and investigate their detection possibilities at the future space-based detectors such as eLISA, ALIA, BBO, DECIGO, U-DECIGO, and ground-based detector aLIGO.KeywordsDark matterGravitational wavePhase transition
