# A Signature of Higher Dimensions at the Cosmic Singularity

@article{McFadden2006ASO, title={A Signature of Higher Dimensions at the Cosmic Singularity}, author={Paul L. McFadden}, journal={arXiv: High Energy Physics - Theory}, year={2006} }

In this thesis we study the dynamics of higher-dimensional gravity in a universe emerging from a brane collision. We develop a set of powerful analytic methods which, we believe, render braneworld cosmological perturbation theory solvable. Our particular concern is to determine the extent to which the four-dimensional effective theory accurately captures the higher-dimensional dynamics about the cosmic singularity. We begin with an overview of the generation of primordial density perturbations…

We explore the problem of braneworld black holes in the heterotic braneworld scenario of Lukas, Ovrut, Stelle and Waldram (LOSW). We show that black string solutions are unstable, and demonstrate…

The current “standard model” of particle physics—which is nearly 25 years old, has much experimental evidence in its favor and is comprised of six quarks, six leptons, four forces, and the as yet unobserved Higgs boson—contains internal indications that it, too, may be just another step along the path toward uncovering the truly fundamental degrees of freedom.
