Strong Electroweak Phase Transition in a Model with Extended Scalar Sector

Strong Electroweak Phase Transition in a Model with Extended Scalar Sector

We consider an extension of the Standard Model (SM) with additional gauge singlets which exhibits a strong first-order phase transition. Due to this first-order phase transition in the early universe gravitational waves are produced. We estimate the contributions such as the sound wave, the bubble w...
