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) \sim g^2(T)T. We find m_e(T) = 2.484(52)T and m_m(T) = 0.466(15) g^2(T) T
