Nuclear Force from String Theory

Abstract: Recent “technology” called holography, or gauge/string duality (AdS/CFT correspondence) found in string theory, makes it possible to compute various quantities of strongly coupled gauge theories. This technology was applied to QCD, and it was found that it describes surprisingly well important properties of low energy QCD, the hadron physics. We apply it further to nuclear physics. In this talk, I review a part of the developments of the holographic QCD, and show a computation of nuclear force at short distance, derived using the holographic QCD, which was done in collaboration with T. Sakai and S. Sugimoto [K. Hashimoto, T. Sakai, and S. Sugimoto, “Holographic Baryons: Static Properties and Form Factors from Gauge/String Duality,”Prog. Theor. Phys. 120 (2008) 1093–1137, arXiv:0806.3122 [hep-th]; K. Hashimoto, T. Sakai, and S. Sugimoto, “Nuclear Force from String Theory,”arXiv:0901.4449 [hep-th]].
