Short description

CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the Universe is made of and how it works. At CERN, the world’s largest and most complex scientific instruments are used to study the basic constituents of matter — the fundamental particles. By studying what happens when these particles collide, physicists learn about the laws of Nature. The instruments used at CERN are particle accelerators and detectors. Accelerators boost beams of particles to high energies before they are made to collide with each other or with stationary targets. Detectors observe and record the results of these collisions. Founded in 1954, the CERN Laboratory sits astride the Franco–Swiss border near Geneva. It was one of Europe’s first joint ventures and now has 20 Member States.

    New ‘super light source’ should allow fascinating insights into atoms

    The ‘Gamma Factory initiative’ – an international team of scientists – is currently exploring a novel research tool: They propose to develop a source of high-intensity gamma rays using the existing accelerator facilities at CERN. To do this, specialized ion beams will be circulated in the S ... more

    Scientists discover long-sought Higgs decay

    Scientists from the two major particle physics experiments ATLAS and CMS at CERN have observed the Higgs boson decaying into two b-quarks, they announced at a joint seminar at CERN today. According to theory, far more than half of all Higgs particles decay into these two quarks, but it is e ... more

    Protons and antiprotons appear to be true mirror images

    CPT invariance means that a system remains unchanged if three fundamental properties are reversed - C (charge), which distinguishes matter from antimatter, P (parity), which implies a 180 degree flip in space, and T (time). It is a central tenet of the standard model, and implies that antim ... more
