Abstract
Perturbative calculations of the free energy of a non-Abelian gauge theory at high temperature break down at order . This problem is solved by constructing a sequence of two effective field theories in which the momentum scales and are integrated out. The free energy is decomposed into contributions from the momentum scales , , and . The three terms are a power series in , a power series in beginning at order , and a power series in beginning at order . In the contribution, the coefficients in the power series can be calculated using lattice simulations of 3-dimensional QCD. Renormalization group equations can be used to sum up the leading logarithms of and of .
