Probing the hidden gauge symmetry breaking through the phase transition gravitational waves

Motivated by the discovery of gravitational waves (GWs) at aLIGO and no evidence of new physicsat current LHC, we discuss that a generic classes of extended new physics models with hidden gaugegroup could undergo one or several times rst-order phase transitions associated with the gaugegroup symmetry breaking during the evolution of the universe, which might produce detectablephase transition GWs signals at future GWs experiments, such as eLISA and BBO.
