The Sub-leading Term of the Strong Coupling Expansion of the Heavy-Quark Potential in a N=4 Super Yang-Mills Plasma

报告人:Zi-Qiang Zhang (CCNU)

Abstract :

Applying the AdS/CFT correspondence, the expansion of the heavy-quark potential of the N=4 supersymmetric Yang-Mills theory at large Nc is carried out to the sub-leading term in the large t’Hooft coupling at a nonzero temperature. The strong coupling corresponds to the semi-classical expansion of the string-sigma model, the gravity dual of the Wilson loop operator, with the sub-leading term expressed in terms of functional determinants of fluctuations. The contribution of these determinants are evaluated numerically.
