During a cosmological first-order phase transition, particles of the plasma crossing bubble walls can radiate gauge boson. The resulting pressure cannot be computed perturbatively for large coupling constant and/or supercooling. We resum real and virtual emissions at all leading-log orders, both analytically numerically using Monte-Carlo simulation. find that radiated bosons are dominantly soft retarding on relativistic is linear in Lorentz boost order parameter, up to log. further quantitatively discuss IR cut-offs, wall thickness effects, impact various approximations entering calculation, comment fate reflected.
