Numerical study of plasmon properties in the SU(2)-Higgs model

Abstract: Using the (effective) classical approximation, we compute numerically time-dependent correlation functions in the SU(2)-Higgs model around the electroweak phase transition, for $m_H \approx m_W$. The parameters of the classical model have been determined previously by the dimensional reduction relations for time-independent correlators. The $H$ and $W$ correlation functions correspond to gauge invariant fields. They show damped oscillatory behavior from which we extract frequencies $\om$ and damping rates $\gm… Show more

“…Lattice formulations of HTL in real time (see e.g. [18][19][20][21][22][23][24][25]) rely on an explicitly separate description of the soft modes as gauge fields and of the hard modes as classical particles. There are two possible approaches used in the literature.…”
