Physics from Extra Dimensions
A brief review of the recent developments in the physics from extra dimensions is given with a focus on the effects of Kaluza-Klein excitations in the Standard Model sector. It is shown that the current accurate data on the Fermi constant and on other electro-weak parameters puts a lower bound on the scale of extra dimensions of∼ 3 TeV, and thus the observation of such dimensions lies beyond th...
متن کاملThe Physics of Extra Dimensions
Lowering the string scale in the TeV region provides a theoretical framework for solving the mass hierarchy problem and unifying all interactions. The apparent weakness of gravity can then be accounted by the existence of large internal dimensions, in the submillimeter region, and transverse to a braneworld where our universe must be confined. I review the main properties of this scenario and i...
متن کاملExtra Dimensions in Particle Physics
Current problems in particle physics are reviewed from the viewpoint of theories possessing extra spatial dimensions.
متن کاملFlavour Physics from Extra Dimensions
We discuss the possibility of introducing an SU(2) global flavour symmetry in the context of flat extra dimensions. In particular we concentrate on the 5-dimensional case and we study how to obtain the flavour structure of the Standard Model quark sector compactifying the fifth dimension on the orbifold S1/Z2 à la Scherk-Schwarz (SS). We show that in this case it is possible to justify the five...
متن کاملParticle Physics Probes Of Extra Spacetime Dimensions
The possibility that spacetime is extended beyond the familiar 3+1-dimensions has intrigued physicists for a century. Indeed, the consequences of a dimensionally richer spacetime would be profound. Recently, new theories with higher dimensional spacetimes have been developed to resolve the hierarchy problem in particle physics. These scenarios make distinct predictions which allow for experimen...
