Query: Thermal gluo-magnetic vacuum of SU(N) gauge theory   The magnetic sector of SU(N) Yang-Mills theory at finite temperature is
studied. At low temperatures, T<2T_c, the analytic expressions for the
temperature dependence of the magnetic correlator, of the magnetic gluon
condensate and of the spatial string tension are obtained. Fair agreement with
lattice calculations for spatial string tension is obtained for SU(2) and SU(3)
gauge theories. The relative contribution given by non-zero Matsubara modes to
the spatial string tension is calculated. At T=2T_c this contribution is of the
order of 5%. The behavior of magnetic correlator at high temperatures is
investigated and it is shown that gluo-magnetic condensate increases with
temperature as <H^2>(T)= const g^8(T) T^4.
