We investigate the temperature dependence of the Landau gauge gluon and ghost
propagators in lattice QCD with two flavors of maximally twisted mass fermions. For these
propagators we provide and analyze data which corresponds to pion mass values between
300 and 500 MeV. For the gluon propagator we find that both the longitudinal and
transversal component change smoothly in the crossover region, while the ghost propagator
exhibits only a very weak temperature dependence. For momenta between 0.4 and 3.0 GeV …
We investigate the temperature dependence of the Landau gauge gluon and ghost propagators in lattice QCD with two flavors of maximally twisted mass fermions. For these propagators we provide and analyze data which corresponds to pion mass values between 300 and 500 MeV. For the gluon propagator we find that both the longitudinal and transversal component change smoothly in the crossover region, while the ghost propagator exhibits only a very weak temperature dependence. For momenta between 0.4 and 3.0 GeV we give a parametrization for our lattice data. It may serve as input for studies which employ continuum functional methods.
