Abstract: The variational cumulant expansion treatment of lattice gauge theory at finite temperature is developed to the lattice SU(2)-Higgs system.The mothod is demonstrated by calculating the expectation value of Polyakov line to the 3rd order approximation.The result is in agreement with the Monte Carlo simulation.The comparison with the mean field results is given.
