Massive gluon propagator at zero and finite temperature
  We report on our study of the infrared gluon propagator for SU(2) lattice gauge theory using large lattice volumes. The observed massive behavior is discussed from the point of view of analytic predictions for the zero-temperature case. Such a behavior is still present as the temperature is switched on, but manifests itself differently in the electric and magnetic channels.
