NonPerturbative Aspects of KaluzaKlein Modes in FiveDimensional Supersymmetric QCD on S^{1}
Abstract
We study the stability of KaluzaKlein (KK) modes in fivedimensional N=1 supersymmetric QCD compactified on S^{1} using the D3brane probe realization. We discover a phenomenon in which the quark KK mode with KK number n = 1 decays while other KK modes are stable. This is contrary to the ordinary assumption that the n = 1 state is the most stable among quark KK modes. In addition, we show that a massive gauge singlet state carrying the KK number exists and is stable. This thus represents a possibility as the identity of dark matter.
