We study the thermodynamics of two-color QCD at high temperature and/ordensity using a dimensionally reduced superrenormalizable effective theory,formulated in terms of a coarse grained Wilson line. In the absence of quarks,the theory is required to respect the Z(2) center symmetry, while the effectsof quarks of arbitrary masses and chemical potentials are introduced via softZ(2) breaking operators. Perturbative matching of the effective theoryparameters to the full theory is carried out explicitly, and it is argued howthe new theory can be used to explore the phase diagram of two-color QCD.
