String Phenomenology


String Phenomenology is the application of String Theory to the real world, through the construction of models meant to resemble the physics we know, with the ultimate aim of explaining all of it and predicting new physics.

Modern String Phenomenology began around 1985 with the discovery of the Type HE String Theory, and Heterotic Models are still a large part of string phenomenology. But after the discovery of D-Branes in 1995, it became apparent that Type II String Theoryies also contained realistic possibilities. M-Theory and F-Theory also contribute to this research.

Heterotic PhenomenologyEdit this section

Heterotic Phenomenology studies  the predictions of Heterotic String Theory compactified on Calabi-Yau Manifolds.  Calabi-Yau Manifolds are Ricci-Flat manifolds, i.e.  R_{\mu\nu} = 0 . The specific Calabi-Yau manifolds in question are with a complex dimensionality of 3, which is equivalent to 6 real dimensions. Compactification of Heterotic String Theoryies on these Calabi-Yau Manifolds, therefore, reduces the dimensionality from 10 to 4. Furthermore, compactification on Calabi-Yau Manifolds retains a Supersymmetry of \mathcal{N}=1, which is an elegant value for the Supersymmetry, due to it's low energy scale.

M-Theory PhenomenologyEdit this section

M-Theory Phenomenology is the study of M-Theory compactified on G(2) Manifolds. G(2) Manifolds are 7-Dimensional, and are similiar to Calabi-Yau Manifolds, but the latter are always even-dimensional, and allow one to use the machinery of complex numbers. BFSS Matrix Theory has a Supersymmetry of \mathcal N=8 , and compactificaation on a G(2) Manifold reduces this to \mathcal         N= 1 Supersymmetry, which is more elegant.
