21 May 2003 | | Journal: | Phys.Rev. D68 (2003) 056001 | | Subject: | hep-ph | | Abstract: | We compute the production rate of lepton pair by static photons at finite temperature at two-loop order. We treat the infrared region of the gluon phase space carefully by using a hard thermal loop gluon propagator. The result is free of infrared and collinear divergences and exhibits an enhancement which produces a result of order $sim e^2 g^3$ instead of $sim e^2 g^4$ as would be expected from ordinary perturbation theory. | | Source: | arXiv, hep-ph/0305226 | | Services: | Forum | Review | PDF | Favorites | |
