Extra Dimensions in Particle Physics
Current problems in particle physics are reviewed from the viewpoint of theories possessing extra spatial dimensions.
متن کاملTopology, Quantum Gravity and Particle Physics
It is argued that quantum gravity has an interpretation as a topological quantum field theory provided a certain constraint from the path integral measure is respected. The constraint forces us to couple gauge and matter fields to gravity for space time dimensions different from 3. We then discuss possible models which may be relevant to our universe.

متن کاملGravity, Particle Physics and Their Unification
Our present world picture is based on two theories: the Standard Model of particle physics and general relativity, the theory of gravity. These two theories have scored astonishing successes. It is therefore quite striking when one learns that this picture of the laws of physics is inconsistent. The inconsistency comes from taking a part of theory, the Standard Model, as a quantum theory and th...
متن کاملLocally Localized Gravity Models in Higher Dimensions
We explore the possibility of generalizing the locally localized gravity model in five space-time dimensions to arbitrary higher dimensions. In a space-time with negative cosmological constant, there are essentially two kinds of higher-dimensional cousins which not only take an analytic form but also are free from the naked curvature singularity in a whole bulk space-time. One cousin is a trivi...
متن کاملOn Higher Derivative Gravity In Two Dimensions
The 2D gravity described by the action which is an arbitrary function of the scalar curvature f(R) is considered. The classical vacuum solutions are analyzed. The one-loop renormalizability is studied. For the function f = R lnR the model coupled with scalar (conformal) matter is exactly integrated and is shown to describe a black hole of the 2D dilaton gravity type. The influence of one-loop q...
