In collaboration with IRFU teams, CMS teams are currently making preparations for the first LHC data acquisition campaign.
On November 14, 2008, the Compact Muon Solenoid (CMS) successfully generated a nominal magnetic field of 4 tesla. This success rewards IRFU efforts for the design and construction of what constitutes the largest superconducting solenoid magnet in the world. Over a period of approximately one month, ... More » |

The ground state of bottomonium.
η b is the name of the particle recently discovered by the physicists working on the BaBar experiment.This ground state of ‘bottomonium’, a collection of particles formed from a bottom quark and an anti-bottom quark, has been sought for over thirty years. It has now been ... More » |

Lorentz symmetry probed in the BaBar experiment
The BaBar experiment running on the PEP-II accelerator at SLAC (California) has been collecting data for ten years and has recorded sufficient events to probe the most subtle aspects of the Standard Model of particle physics and quantum field theory. By analysing the behaviour over time of the ... More » |

Searching cosmic neutrinos
The last two lines of the ANTARES detector were connected and powered at a depth of 2500 m on the Mediterranean seabed during the night of May 30, 2008. This brings the number of lines to twelve and completes the construction phase of the largest underwater neutrino telescope ever built. The lines ... More » |

The shape of an atomic nucleus reflects the shell structure of the protons and neutrons of which it is formed. If the shells are completely filled, we speak of a "magic" nucleus, which is spherical in shape. Most nuclei, however, tend to be deformed because their shells are only ... More » |

Shortly after the LHC started up on the 10th September 2008 at 9:30 am, the detectors recorded the first events resulting from proton collisions in the beam detectors. The data processing scheme that had been planned for such a long time immediately came into action with the distribution of data ... More » |
