Abstract

We study the dynamics of electroweak bubbles in the scenario of a strong first-order inverse electroweak phase transition at the TeV scale involving the global structure of the nonlinear sigma field in the littlest Higgs model with T parity. Employing the one-loop-order finite-temperature effective potential, we find that the pressure in the symmetric phase, i.e., inside the bubble, is always greater than that in the asymmetric phase, i.e., outside the bubble, so that the bubbles are expanding. By calculating the fluid velocities in the two phases we arrive at the condition of a supersonic deflagrated motion of the bubble walls. We then discuss the generation of gravitational waves from the collisions of such bubbles as well as from the turbulence of the plasma.
