SU(5)+Adjoint Higgs at Finite Temperature
Abstract
I present a threedimensional effective theory that describes the hightemperature equilibrium behavior of the SU(5) theory accurately, but is much easier to study using nonperturbative methods than the original fourdimensional one. The effective theory is obtained by perturbatively integrating out the superheavy Matsubara modes as well as the heavy temporal component of the gauge field. Regardless of the particle spectrum of the original theory, the resulting threedimensional theory contains only a gauge field and an adjoint Higgs field. The phase diagram of the theory is analysed perturbatively and it is shown to have a cellular structure in threedimensional parameter space.
