Abstract
Within the classical approximation we calculate the static Q (Q) over bar p otential via the AdS/CFT relation for nonzero temperature and arbitrary int ernal orientation of the quarks. We use a higher order curvature corrected target space background. For timelike Wilson loops there arises a critical line in the orientation-distance plane which is shifted to larger distances relative to the calculation with uncorrected background. Beyond that line there is no Q (Q) over bar-force. The overall vanishing of the force for an tipodal orientation known from zero temperature remains valid. The spacelik e Wilson loops yield a string tension for a (2+1)-dimensional gauge theory, independent of the relative internal orientation, but sensitive to the bac kground correction.
