Real-Time History of the Cosmological Electroweak Phase Transition.

We study numerically the real-time history of the cosmological electroweak phase transition, as it may take place in the Standard Model or in MSSM for mH ∼mW according to recent lattice results. We follow the nucleated bubbles from the initial stages of acceleration and rapid growth, through collisions with compression waves resulting in slowing down and reheating to Tc, until the final stages of slow growth and evaporation. We find that collisions with compression waves may make the bubble walls oscillate in the radial direction, and that reheating to Tc takes generically place.
