Soft dilepton production and hard thermal loops
Abstract
Description
The Hard Thermal Loop expansion, is an attractive theory, but it reveals difficulties when one uses it as a perturbative scheme. To illustrate this we use the HTL expansion to calculate the two loop corrections for soft virtual photons. The resulting corrections are of the same order as the 1-loop correction.
