## Abstract

Finite-size effects on lattice Monte Carlo measurements of the screening mass in high temperature QCD are studied by computing the static limit of the gluon polarization tensor p{cyrillic}_{μν} on the lattice. Doing the sum over the discrete frequencies p_{0} analytically permits one to write the result in a very simple form as a threefold sum over p_{i} and closely resembling the continuum result. The magnitude of the plasmon term in the pressure of an interacting quark-gluon gas on the lattice is estimated and shown to be small for lattices in current use. The same techniques are applied to the calculation of the energy density and the quark number susceptibility ∂n_{B} (T, μ = 0) ∂_{μ} for an ideal gas of quarks and gluons on the lattice.
