Abstract
Experiments in particle physics are nowadays feasible exclusively as joint endeavours of huge collaborations in a few international centres. Slovenian scientists conduct their experiments as members of four such collaborations: ATLAS, CPLEAR and DELPHI at the European Organization for Nuclear Research (CERN) near Geneva and HERA-B at DESY in Hamburg. Research with the DELPHI spectrometer at CERN's Large Electron-Positron collider (LEP) comprises measurements of electron-positron interactions, initially at 90 GeV, the energy of the Z0 boson, and recently at energies surpassing 200 GeV. Physics issues include precision tests of the Standard model of electroweak and strong interactions, including triple-gauge couplings between gauge bosons and search for the Higgs particle. Slovenian physicists take part in the maintenance of the semiconductor tracker and the ring imaging Cherenkov detector. Among physics topics, their main interest is in anomalous gauge couplings, search for charged Higgs bosons and forward-backward asymmetries in Z0 › b b decays. Measurements of the discrete symmetries, CP, T and CPT in the neutral kaon system are performed with the CPLEAR spectrometer. Among the highlights feature the first direct observation of time-reversal violation in the micro-world and the most precise test of CPT invariance at the level of 10-18 GeV. Discovery of CP violation in the system of neutral B mesons is the aim of the HERA-B experiment. Slovenian researchers lead the effort in construction, commissioning and running of one of the most elaborate detectors – the Ring Imaging CHerenkov (RICH) detector and are heavily involved in physics analysis of emerging data. The main experiment, setting the stage for a breakthrough into the yet unexplored energy range up to 1 TeV, is ATLAS, being constructed for a start of operation at the Large Hadron Collider (LHC) at CERN in 2005. Among the 2000 scientists from 150 institutes collaborating on this giant project, Slovenian researchers took responsibilities in construction of the SemiConductor Tracker (SCT). More than 60 m2 of processed silicon wafers will form a detector serving for charged particle tracking in the heart of the ATLAS spectrometer. Slovenian industry, with R&D involvement from our scientists, will produce all the power distribution cables for the SCT as large-scale lithography on aluminium-Kapton substrates. Radiation hardness of silicon is among the main detector R&D issues with a strong Slovenian participation. With ATLAS, as well as in collaboration with CERN's RD-39 and RD-48 projects, Slovenian researchers made good use of the TRIGA research reactor at the Jožef Stefan Institute, promoting it to a reference neutron irradiation site in these endeavours.
