Background: The Large Hadron Collider (LHC) under construction at CERN will open up an entirely new domain in the exploration of the structure of matter at the smallest possible scale. The discovery of many new particles at LHC will shed light on one of the fundamental issues in elementary particle physics: the understanding of the dynamics responsible for the electroweak symmetry breaking (what triggers the differentiation between electromagnetism and beta radioactivity whereas they come from the same interaction at high energy?), and the origin of masses of elementary particles (why are elementary particles massive, why are their masses so different?). These issues also have cosmological implications for the history of the early Universe.
Content The dominant theme of the School is the study of the observable consequences of possible electroweak symmetry breaking patterns and their signatures in the complex detectors of the LHC experiments ATLAS and CMS. The topic is therefore at the interface between theory and experiment. Starting from the results of the phenomenological analysis of present data (LEP at CERN and Tevatron at FERMILAB, USA), strategies will be developed to understand how future experimental results will unravel possible patterns of symmetry breaking.
Objectives The proposed school aims at preparing young physicists, both theoreticians and experimentalists, to the analysis and interpretation of data to be collected at the LHC when it starts operating in 2005. The problems to be studied are: what are the signals of new physics? Could they be hidden by the background? How to optimise these signals? Various analytical and computational tools will be used and applied to specific cases.
