In this course of 32 lectures the physical problems investigated on the colliders LEP, HERA and Tevatron will be discussed. Central to these investigations is the exploration of the Standard Model of elementary particle physics and the search for the limits of its validity.
The proton-antiproton collider Tevatron has been in operation since 1987. Its most outstanding achievement has been the discovery of the top quark.
The Large Electron-Positron collider (LEP) at the European Centre for Elementary Particle Physics CERN has been in operation since 1989. In its first phase LEP was operated at an energy corresponding to the mass of the Z boson, about 90 GeV. For several years LEP produced precision measurements of parameters of the Standard Model. Based on these results, it could be firmly established that there are only three generations of fermions. Searches for physics beyond the SM have proved negative. In phase 2, since 1996, LEP was operated at higher energies, above the threshold for W boson pair production.
HERA is an electron-proton collider with a centre-of-mass energy of about 300 GeV. This high energy extends the kinematical region of deep inelastic scattering by more than an order of magnitude, compared with previous fixed-target experiments. In the five years of operation HERA physics has yielded important insights into the structure of the proton. Some recent results have raised speculations of first sightings of physics beyond the SM.
The lectures will consist of a presentation of the Standard Model, always keeping close to the corresponding phenomenology. The colliders and detectors will be discussed in sufficient detail to give confidence in the scientific soundness of their results. A major part of the course will be concerned with deep inelastic scattering and the structure of the proton.
