| Research Abstract |
We have shown that in the framework of higher-dimensional gauge/gravity theories N=2 quantum-mechanical supersymmetry is hidden, and that the origin of the supersymmetry is given by higher-dimensional gauge symmetry and/or higher-dimensional general coordinate invariance. Further, the supersymmetry is found to be closely related to gauge symmetry breaking. We also found that gauge symmetries can be broken even at high temperature in higher-dimensional gauge theories contrary to our expectations.
