Abstract

The D-brane spectrum of a 2×2 Calabi-Yau three-fold orbifold of toroidally compactified Type IIA and Type IIB string theory is analysed systematically. The corresponding K-theory groups are determined and complete agreement is found. New kinds of stable non-BPS D-branes are found, whose stability regions are far more complicated than the previously discussed non-BPS D-branes. The decay channels of non-BPS D-branes beyond their stability regions are identified. Finally the T-dual orbifold is analysed and a suitable K-theory is found.
