The long wavelength limit of hard thermal loop effective actions

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/224253We derive a closed form expression for the long wavelength limit of the effective action for hard thermal loops in an external gravitational field. It is a function of the metric, independent of time derivatives. It is compared and contrasted with the static limit, and with the corresponding limits in an external Yang-Mills field.5 pagesHigh Energy Physics - TheoryThe long wavelength limit of hard thermal loop effective actionstext
