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 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 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...

Current problems in particle physics are reviewed from the viewpoint of theories possessing extra spatial dimensions.
متن کاملNew Higgs Signals from Flavor Physics in Large Extra Dimensions
In a realistic theory with large extra dimensions and TeV scale gravity, there are often other particles living in the extra dimensions in addition to gravitons. A well motivated candidate is the flavon in a flavor theory which explains the smallness of the fermion masses by the large volume of the extra dimensions. The flavon interactions involve the Higgs field and can therefore give rise to ...
