Massless Spectra of Three Generation U(N) Heterotic String Vacua
Ralph Blumenhagen, Sebastian Moster, Rene Reinbacher +1
We provide the methods to compute the complete massless spectra of a class of recently introduced supersymmetric E8 x E8 heterotic string models which invoke vector bundles with U(…
Non-perturbative SQCD Superpotentials from String Instantons
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +2
The Affleck-Dine-Seiberg instanton generated superpotential for SQCD with Nf=Nc-1 flavours is explicitly derived from a local model of engineered intersecting D6-branes with a sing…
Adding flavour to the Polchinski-Strassler background
Riccardo Apreda, Johanna Erdmenger, Dieter Lust +1
As an extension of holography with flavour, we analyze in detail the embedding of a D7-brane probe into the Polchinski-Strassler gravity background, in which the breaking of confor…
Four-dimensional String Compactifications with D-Branes, Orientifolds and Fluxes
Ralph Blumenhagen, Boris Kors, Dieter Lust +1
This review article provides a pedagogical introduction into various classes of chiral string compactifications to four dimensions with D-branes and fluxes. The main concern is to…
Topological twisting of conformal supercharges
Jeong-Hyuck Park, Dimitrios Tsimpis
Putting a twisted version of N=4 super Yang-Mills on a curved four-dimensional manifold generically breaks all conformal supersymmetries. In the special case where the four-manifol…
Quantum Hall Effect on the Flag Manifold F_2
Mohammed Daoud, Ahmed Jellal
The Landau problem on the flag manifold is analyzed from an algebraic point of view. The involved magnetic background is induced by two U(1) abe…
