Signals from extra dimensions decoupled from the compactification scale
F. del Aguila, J. Santiago
Abstract
Multilocalization provides a simple way of decoupling the mass scale of new physics from the compactification scale of extra dimensions. It naturally appears, for example, when localization of fermion zero modes is used to explain the observed fermion spectrum, leaving low energy remnants of the geometrical origin of the fermion mass hierarchy. We study the phenomenology of the simplest five dimensional model with order one Yukawa couplings reproducing the standard fermion masses and mixing angles and with a light Kaluza-Klein quark Q2/3 saturating experimental limits on Vtb and mQ, and then with observable new effects at Tevatron.
