The gluon propagator at high temperature

We study the gluon propagator in Landau gauge in the deconfined phase of SU(2) gauge theory. From the long-distance behaviour of correlation functions of temporal and spatial components of the gauge fields we extract electric ( m_e) and magnetic ( m_m) screening masses. For temperatures larger than twice T_c we find no additional temperature dependence in {m _e(T) }/{T}, while {m _m(T) }/{T} drops with increasing temperature. The decrease is consistent with the expected behaviour, m_m( T) ∼ g²( T) T. We find m_e( T) = 2.484(52) T and m_m( T) = 0.466(15) g²( T) T.
