摘要：We compute, to two loops in pertubation theory, the fermionic contribution to rectangular RT
Wilson loops, for different values of R and T.
We use the overlap fermionic action. We also employ the clover action, for comparison with
existing results in the literature. In the limit R;T !¥ our results lead to the shift in the b-quark
mass. We also evaluate the perturbative static potential as T !¥.
