Serial title, monograph or event: | EPJ Web of Conferences | Volume: | 175 | Abstract: | We report on the lattice computation of the Landau gauge gluon propagator at finite temperature, including the non-zero Matsubara frequencies. Moreover, the corresponding K\"all\'en-Lehmann spectral density is computed, using a Tikhonov regularisation together with the Morozov discrepancy principle. Implications for gluon confinement are also discussed. | Description: | 5 pages, 5 figures, Lattice 2017 proceedings | URI: | https://hdl.handle.net/10316/107551 | ISSN: | 2100-014X | DOI: | 10.1051/epjconf/201817507038 | Rights: | openAccess |
