We analyse the dynamics of the relativistic bubble expansion during the first order phase transition focusing on the ultra relativistic velocities γ≫ 1. We show that fields much heavier than the scale of the phase transition can significantly contribute to the friction and modify the motion of the bubble wall leading to interesting phenomenological consequences. NLO effects on the friction due to the soft vector field emission are reviewed as well.

• Towards an all-orders calculation of the electroweak bubble wall velocity (2020, background): “If the masses are hierarchical, mc,s mc,h, then the transverse momentum integral has a logarithmic enhancement, ∫ d(2)~k⊥|M (0) a→bc|(2) ∝ log(m(2)c,h/m(2)c,s) [18].”
