Finite temperature NLO corrections in relativistic scatterings: Implications for dark matter freeze-in
Aps.org·October 5, 2026
We study the next-to-leading order (NLO) virtual and thermal corrections to relativistic $2\ensuremath{\rightarrow}2$ scattering processes involving scalar particles in the early Universe thermal plasma. Taking the example of freeze-in production of scalar da…
