  We investigate the dynamic relaxation for SU(2) gauge theory at finite
temperatures in (3+1) dimensions. Using the Hybrid Monte Carlo algorithm, we
examine the time dependence of the system in the short-time regime. Starting
from the ordered state, the critical exponents beta, nu and z are calculated
from the power law behaviour of the Polyakov loop and the cumulant at or near
the critical point. The results for the static exponents are in agreement with
those obtained from simulations in equilibrium and those of the
three-dimensional Ising model. The value for the dynamic critical exponent was
determined with z=2.0(1).
