Brane World
Zurab Kakushadze, S. -H. Henry Tye
In string theory, the brane world scenario, where the Standard Model gauge and matter fields live inside some branes while gravitons live in the bulk, can be a viable description o…
Bose-Fermi Degeneracy and Duality in Non-Supersymmetric Strings
Gary Shiu, S. -H. Henry Tye
Following Kachru, Kumar and Silverstein, we construct a set of non-supersymmetric Type II string models which have equal numbers of bosons and fermions at each mass level. The mode…
Three Generations in Type I Compactifications
Zurab Kakushadze, S. -H. Henry Tye
Generalizing the recent work on three-family Type I compactifications, we classify perturbative Type I vacua obtained via compactifying on the T^6/Z_2 X Z_2 X Z_3 orbifold with all…
TeV Scale Superstring and Extra Dimensions
Gary Shiu, S. -H. Henry Tye
Utilizing the idea of extra large dimensions, it has been suggested that the gauge and gravity couplings unification can happen at a scale as low as 1 TeV. In this paper, we explor…
Type IIB Orientifolds, F-theory, Type I Strings on Orbifolds and Type I - Heterotic Duality
Zurab Kakushadze, Gary Shiu, S. -H. Henry Tye
We consider six and four dimensional supersymmetric orientifolds of Type IIB compactified on orbifolds. We give the conditions under which the perturbative world-sheet…
Type IIB Orientifolds with NS-NS Antisymmetric Tensor Backgrounds
Zurab Kakushadze, Gary Shiu, S. -H. Henry Tye
We consider six dimensional N=1 space-time supersymmetric Type IIB orientifolds with non-zero untwisted NS-NS sector B-field. The B-field is quantized due to the requirement that t…
