Description
In a first order electroweak phase transition bubbles of Higgs phase
expand into the symmetric phase. Particles hitting a bubble wall
cause friction and slow down the expansion. In some models this can be
insufficient to compensate the pressure difference between the two
phases. Then the bubble wall would accelerate indefinitely, it would 'run
away'. However, particles crossing the bubble wall can emit transition
radiation, causing additional friction which prevents runaway.
