Finite temperature gluon propagator in Landau gauge: non-zero Matsubara frequencies and spectral densities


  • Dr. Paulo SILVA

Primary authors


We report on the lattice computation of the Landau gauge gluon propagator at finite temperature, including the non-zero Matsubara frequencies. Furthermore, the Källén-Lehmann representation is inverted and the corresponding spectral density evaluated using a Tikhonov regularisation together with the Morozov discrepancy principle. Implications for gluon confinement are also discussed.
