Finite temperature gluon self-energy in a class of temporal gauges | | F. T. Brandt

4 Oct 1999 | | Journal: | Phys.Rev. D61 (2000) 125014 | | Subject: | hep-th hep-ph | | Abstract: | The approach which relates thermal Green functions to forward scattering amplitudes of on-shell thermal particles is applied to the calculation of the gluon self-energy, in a class of temporal gauges. We show to all orders that, unlike the case of covariant gauges, the exact self-energy of the gluon is transverse at finite temperature. The leading T^2 and the sub-leading ln(T) contributions are obtained for temperatures T high compared with the external momentum. The logarithmic contributions have the same structure as the ultraviolet pole terms which occur at zero temperature. | | Source: | arXiv, hep-th/9910027 | | Services: | Forum | Review | PDF | Favorites | |
