Improved heavy quark potential at finite temperature from anti-de Sitter supergravity

We improve the heavy quark potential, extracted from the Wilson loop average in the Ads/CFT approach by taking the quantum fluctuation of the only radial coordinate of Ads5 which is transverse to the world-sheet of the classical Nambu-Goto string in the static gauge, and obtain the universal Lüscher-Symanzik-Weisz/Lüscher term.
