Particle Physics Group

Organisation profile:The Elementary Particle Physics group (EDF) has a long tradition in experimental and phenomenological research of high-energy collisions produced at the highest-energy particle accelerators and colliders in the world. The emphasis lies on multi-particle production processes, the experimental study of quantumchromodynamics, the mechanism of diffractive collisions, Higgs search and supersymmetry. The group presently participates in - the H1 experiment at the HERA electron/positron-proton collider in DESY, Hamburg. Recent activities involved the installation of a novel proton spectrometer in the HERA proton beamline for the study of virtual photon diffraction. -the CMS experiment at the Large Hadron Collider, now under construction in CERN, Geneva, and due to start up in 2007. The group is actively involved in the large international team responsible for the construction of the (forward) central tracking detector, built from silicon sensors. The central tracker contains about 250 square metres of such Si detectors. The group played a leading role in the design and construction of automatic long-term-teststations for the sensors, and in read-out electronics for the CMS-tracket data-acquisition system. Other activities include physics and detector design studies for the CMS 'Forward Physics' programme.
