Abstract
We study out-of-equilibrium quasi-particle distributions of the Higgs and W fields during the zero-temperature tachyonic electroweak transition that has been assumed in recent scenarios of baryogenesis. Approximating the process by a fast quench, we perform classical real-time lattice simulations in the SU(2)-Higgs model. The emerging quasi-particle numbers and energies are then used to determine the effective temperatures, chemical potentials and masses of the particles shortly after the transition.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

When we wish to measure particle numbers in the gauge field we use standard gauge fixing techniques (see Appendix [ref]) and then measure the connected two point functions [ref] [equation] With $D_L^A(k,t) = 0$ in Coulomb gauge we define the gauge field particle number as [equation] This quantity is not gauge invariant and so we also present the power spectrum of the energy density in the gauge field in our results.
