The Standard Model on a D-brane
نویسندگان
چکیده
We present a consistent string theory model which reproduces the Standard Model, consisting of aD3-brane at a simple orbifold singularity. We study some simple features of the phenomenology of the model. We find that the scale of stringy physics must be in the multi-TeV range. There are natural hierarchies in the fermion spectrum and there are several possible experimental signatures of the model. e-mail: [email protected] e-mail: [email protected] e-mail: [email protected]

The massive Elko spinor field in the de Sitter braneworld model
The Elko spinor field is a spin 1/2 fermionic quantum field with a mass dimension introduced as a candidate of dark matter. In this work, we study the localization of Elko fields on a de Sitter thick brane constructed by a canonical or phantom scalar field. By presenting the mass-independent potentials of Kaluza-Klein (KK) modes in the corresponding Schrödinger equations, it is shown that the E...
متن کاملSpherically Symmetric Solutions in a New Braneworld Massive Gravity Theory
In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
متن کاملD-branes in Standard Model building, Gravity and Cosmology
D-branes are by now an integral part of our toolbox towards understanding nature. In this review we will describe recent progress in their use to realize fundamental interactions. The realization of the Standard Model and relevant physics and problems will be detailed. New ideas on realizing 4-dimensional gravity use the brane idea in an important way. Such approaches will be reviewed and compa...
متن کاملMore about the Standard Model at Intersecting Branes 1
Intersecting D-brane models seem to be one of the most promising avenues to embed the Standard Model physics within the string context. We review here different aspects of these models. Topics include the question of SUSY and quasi-SUSY in intersecting brane models, model-building, the brane recom-bination interpretation of the SM Higgs mechanism, Yukawa couplings, the lowering of the string sc...
متن کاملThe anomalous magnetic moment of the muon in the D-brane realization of the Standard Model
The anomalous magnetic moment of the muon is evaluated in the D-brane realization of the Standard Model. It is pointed out that the massive anomalous U(1) gauge bosons predicted, give extra contributions that are compatible with current experimental data. ∗Unité mixte du CNRS and de l’Ecole Polytechnique, UMR 7644
متن کاملSurveying Standard Model Flux Vacua on T 6 / Z 2 ×
We consider the SU(2)L × SU(2)R Standard Model brane embedding in an orientifold of T /Z2×Z2. Within defined limits, we construct all such Standard Model brane embeddings and determine the relative number of flux vacua for each construction. Supersymmetry preserving brane recombination in the hidden sector enables us to identify many solutions with high flux. We discuss in detail the phenomenol...
