Outline of Final Research Achievements

We studied non-supersymmetric gauge theories using superstring theory. In particular, we mainly considered S-duality in non-supersymmetric gauge theory and holographic dual of 3 dim Yang-Mills-Chern-Simons (YMCS) theory. For the former, we found a new S-duality that relates strongly coupled gauge theory and weakly coupled gauge theory using string theory, and showed that the color confinement and dynamical symmetry breaking can be understood in terms of the weakly coupled description. For the latter, we analyzed the YMCS theory with domain walls using holography and found various new features of this system including a new kind of phase transition.
