Continuing our recent work hep-th/0411173, we study the statistics of four-dimensional, supersymmetric intersecting D-brane models in a toroidal orientifold background. We have performed a vast computer survey of solutions to the stringy consistency conditions and present their statistical implications with special emphasis on the frequency of Standard… (More)

We investigate the statistics of the phenomenologically important D-brane sector of string compactifications. In particular for the class of intersecting D-brane models, we generalise methods known from number theory to determine the asymptotic statistical distribution of solutions to the tadpole cancellation conditions. Our approach allows us to compute… (More)

Using previous results on the statistics of intersecting D6-brane models on T 6 /Z ′ 6 we analyse solutions that resemble the gauge group and matter content of the supersymmetric standard model. In particular the structure of the hidden sector, the gauge coupling constants and chiral exotic matter content are computed and classified for all possible… (More)

Recently spatially localized anomalies have been considered in higher dimensional field theories. The question of the quantum consistency and stability of these theories needs further discussion. Here we would like to investigate what string theory might teach us about theories with localized anomalies. We consider the Z 3 orbifold of the heterotic E 8 × E… (More)

We provide a complete classification and statistical analysis of all type IIA orientifold compactifications with intersecting D6–branes on the orbifold T 6 /Z ′ 6. The total number of four dimensional N=1 supersymmetric models is found to be O(10 23). After a statistical analysis of the gauge sector properties of all possible solutions, we study three… (More)

We analyze four-dimensional, supersymmetric intersecting D-brane models in a toroidal orientifold background from a statistical perspective. The distribution and correlation of observables, like gauge groups and couplings, are discussed. We focus on models with a Standard Model-like gauge sector, derive frequency distributions for their occurrence and… (More)

In this article, which is based on the first part of my PhD thesis, I review the statistics of the open string sector in T 6 /(Z2 × Z2) orientifold compactifications of the type IIA string. After an introduction to the orientifold setup, I discuss the two different techniques that have been developed to analyse the gauge sector statistics, using either a… (More)

An analysis of a special class of type II string theory compactifications is presented. We focus on recent work in one particular orientifold background of intersecting brane models and the resulting four dimensional gauge group and matter content. Special attention is paid to solutions that resemble the gauge group of the MSSM. Statistical correlations… (More)

The recent discovery of a number of genes involved in familial forms of Parkinson's disease (PD) has moved the use of model genetic organisms to the frontline. One avenue holding tremendous potential to find therapies against human diseases is the use of intact living systems where complex biological processes can be examined. Despite key differences that… (More)

We consider topological sigma models with generalized Kähler target spaces. The mirror map is constructed explicitly for a special class of target spaces and the topo-logical A and B model are shown to be mirror pairs in the sense that the observables, the instantons and the anomalies are mapped to each other. We also apply the construction to open… (More)
