Description
We simulate a theory with N_f=2 heavy quarks of mass M. At energies much
smaller than M the heavy quarks decouple and the theory can be described
by an effective theory which is a pure gauge theory to leading order in 1/M. We present results for the mass dependence of ratios such as t_0(M)/t_0(0). We compute these ratios from simulations and compare them to the perturbative prediction. The latter relies on a factorization formula for the ratios which is valid to leading order in 1/M in the low energy effective theory.
