Topological Defects and Gravity in Theories with Extra Dimensions
Recent proposals of large and infinite extra dimensions triggered a strong research activity in theories in which our universe is considered as a sub-manifold of some higherdimensional space-time, a so-called 3-brane. In this context, it is generally assumed that some mechanism is at work which binds Standard Model particles to the 3-brane, an effect often referred to as the localization of mat...
متن کاملTheories with Extra Dimensions
We review some aspects of theories with compact extra dimensions. We consider the motivation and the theoretical basis of Large, Universal and Warped Extra Dimensions. We focus on those aspects that are potentially relevant in the phenomenology at colliders. THE NEED FOR PHYSICS BEYOND THE STANDARD MODEL Although the Standard Model (SM) is in quite good agreement with experiment so far, there a...

Ju ly 20 0 8 je a n -f ra n co is P o d ev in on the very smallest scales—the voids in between the smallest known elementary particles—by quantum laws and possibly explain it in terms of some fundamental constituents. Superstring theory is often described as the leading candidate to fill this role, but it has not yet provided an answer to any of these pressing questions. Instead, following its ...
متن کاملAlternative Theories of Gravity
ACKNOWLEDGEMENTS This work would not have been possible without the help of a lot of people. I would like to thank my family and friends for their encouragement, my collaborators David Mota and Robert Scherrer for their hard work and my office mate Simon West for innumerable delightful lunches. Most of all I would like to thank my supervisor, John Barrow, for his constant support, his guidance ...
متن کاملNonholonomic Black Ring and Solitonic Solutions in Finsler and Extra Dimension Gravity Theories
We study stationary configurations mimicking nonholonomic locally anisotropic black rings (for instance, with ellipsoidal polarizations and/or imbedded into solitonic backgrounds) in three/six dimensional pseudo–Finsler/ Riemannian spacetimes. In the asymptotically flat limit, for holonomic configurations, a subclass of such spacetimes contains the set of five dimensional black ring solutions w...
