Title: "Extra dimensions at the Large Hadron Collider"
------------------------------------------------------------------------------------------------------------------
Abstract:

During the last ten years, many authors used the Extra Dimensions (ED) paradigm to tackle old fundamental physics
problems such as the hierarchy problem, the origin of electroweak symmetry breaking, the generation of the fermion
mass hierarchy, the origin of dark matter and the nature of the cosmological constant. In some ED models, new
phenomenology is predicted at the TeV scale, which is experimentally very interesting in the context of the Large
Hadron Collider (LHC), which will cover the range from 100 GeV to few TeV. In this seminar, we present an overview
of the existing ED models and the sensitivity of the LHC experiments to some of them. Given the upcoming first 
Physics Run of the LHC, we focus on searches with early data at the Compact Muon Solenoid (CMS) experiment.
