Wess–Zumino actions and Dirichlet boundary conditions for super p-branes with exotic fractions of supersymmetry

, 2003
The general solutions in the models of closed and open superstring and super p-branes with exotic fractions of the N=1 supersymmetry are considered and the spontaneously broken character of the OSp(1,2M) symmetry of the models is established. It is shown

Orientifold Calabi-Yau threefolds: divisor exchanges and multi-reflections

Journal of High Energy Physics
Using the Kreuzer-Skarke database of 4-dimensional reflexive polytopes, we systematically constructed a new database of orientifold Calabi-Yau threefolds with h 1,1(X) ≤ 12.

Emergence of CY triple intersection numbers in M-theory

Journal of High Energy Physics
To give more credence to the M-theoretic Emergence Proposal it is important to show that also classical kinetic terms in a low energy effective action arise as a quantum effect from integrating out light towers of states.

N=1 supersymmetric SU(4) x SU(2)(L) x SU(2)(R) effective theory from the weakly coupled heterotic superstring [PDF]

, 1999
In the context of the free-fermionic formulation of the heterotic superstring, we construct a three-generation N = 1 supersymmetric SU(4) x SU(2)(L) x SU(2)(R) model supplemented by an SU(8) hidden gauge symmetry and five Abelian factors.

New string theory vacua with suppressed proton decay

, 2003
In this thesis we construct new heterotic superstring vacua with suppressed proton decay. More concretely, we construct Calabi-Yau threefolds Z with fundamental group [special characters omitted].

Physics implications of perturbative string vacua

, 1999
A systematic investigation of the phenomenology of a class of perturbative string models is presented. We first analyze perturbative heterotic superstring models which have the gauge group and particle content of the minimal supersymmetric standard model

One loop phenomenology of type II string theory: intersecting d-branes and noncommutativity [PDF]

, 2007
We examine one loop amplitudes for open and closed strings in certain D-brane configurations, and investigate the consequences for phenomenology. Initially we consider open strings at D6-brane intersections.
