A new picture for 4-dimensional 'spacetime' from intersecting D-branes on the T^9
Tassilo Ott
A factorization of spacetime of the form M^3xM^3xM^3 is considered in this paper as the closed string background in type IIA. The idea behind this construction is that each M^3 mig…

Catching the phantom: the MSSM on the Z6-orientifold
Tassilo Ott
These lecture notes give a short introduction of the derivation of the supersymmetric standard model on the Z6-orientifold as published in hep-th/0404055. Untwisted and twisted cyc…

Supersymmetric Intersecting Branes on the Type IIA T^6/Z_4 orientifold
Ralph Blumenhagen, Lars Goerlich, Tassilo Ott
We study supersymmetric intersecting D6-branes wrapping 3-cycles in the Type IIA T^6/Z_4 orientifold background. As a new feature, the 3-cycles in this orbifold space arise both fr…
