Scalar field damping at high temperatures

HIGHLIGHTS

• who: Fakultu00e4t fu00fcr, Physik and Fakultu00e4t fu00fcr, Physik from the Bielefeld, Bielefeld, Germany have published the article: Scalar field damping at high temperatures, in the Journal: (JOURNAL) of 21/09/2022
• what: A slowly moving homogeneous scalar field u03c6 interacting with a thermal plasma drives it slightly out of equilibrium, giving rise to dissipation and damping.

SUMMARY

Scalar fields may play an important role in the early Universe. Several authors have applied 1- or 2-loop approximations with resummed propagators containing a finite width (see e_g_[17-20]), which gives rise . . .
