During the second half of 2008, the Large Hadron Collider (LHC) at CERN is foreseen to deliver its first proton-proton collisions at a centre-of-mass energy of 10-14 TeV. This unprecedented energy, and the very high luminosity, will push elementary particle physics into a new age, recreating conditions as they were just after the Big Bang. The potential of this machine to search for new phenomena surpassing our current understanding, as described by the Standard Model of particle physics, are excellent and exciting. The ATLAS detector, designed to measure the LHC collisions, is ready to enter this new domain. I believe that the theory of supersymmetry provides the best motivated framework for a search for new physics. If supersymmetry is realized in nature, it may solve urgent problems in particle physics and cosmology, such as the nature of dark matter, or the origin of the asymmetry between matter and anti-matter in the universe. I propose to build a strong group that will first pursue the discovery of supersymmetry with the ATLAS detector in an inclusive way, and subsequently unravel the behaviour of individual supersymmetric particles by focussing on heavy flavour quarks and leptons: the top and bottom quarks, and the tau lepton. I believe that such a study of supersymmetric heavy-flavour physics is innovative and urgent, and also challenging. The team will make use of our investments in ATLAS as well as the Dutch Grid computing facilities, and will have strong links to astroparticle physics and advanced data analysis groups.
