Phys. Rev. Lett. 90, 091601 (2003) [4 pages]Hadron Masses and Screening from Anti–de Sitter Space Wilson LoopsReceived 15 November 2002; published 6 March 2003 We show that in strongly coupled N=4 supersymmetric Yang-Mills conformal theory the binding energy of a heavy and a light quark is independent of the strength of the coupling constant. As a consequence we are able to show that in the presence of light quarks the analog of the QCD string can snap and color charges are screened. The resulting neutral mesons interact with each other only via pion exchange and we estimate the masses of those states. © 2003 The American Physical Society URL:
