CERN, LHC and the Particle Adventure




Bernhard Meirose


To raise young people's awareness and appreciation of the particle physics research done at CERN


This talk was given to students at Bladins International School of Malmö (Sweden) on 2011-04-06. The aim of the talk is to give an overview of the particle physics research done at CERN. I start from a historical point of view. I first talk about the history of CERN and of the key experiments of Rutherford. I motivate (using very basic quantum physics ) the need of more energy to "see smaller things" that lead to modern accelerators. I explain how accelerators work and the possibility of producing new particles with it. I motivate why scientists want to produce these new particles by briefly presenting the Standard Model and some of its famous open questions, including a discussion of the necessity to find the Higgs particle. I present the example of Supersymmetry as a possible scenario to address problems left unsolved by the Standard Model and discuss how one would detect it by briefly discussing particle detectors and in particular the ATLAS experiment. I conclude by giving my own view of why the knowledge gained by fundamental research is important and healthy for our society.
The language is English and the talk is aimed at students of 16-17 years old and takes approximately 45 minutes for delivery.
