Limiting First Order Phase Transitions in Dark Gauge Sectors from Gravitational Waves experiments

Abstract

We discuss the possibility to indirectly test First Order Phase Transitions of hidden sectors. We study the interesting example of a {\it dark standard model} with a deformed parameter space in the Higgs potential. A dark electroweak phase transition can be limited from next future experiments like eLISA and DECIGO.
