BaBar discovers eta-sub-b
28-08-2008
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 »
Successful acquisition of cosmic event data by CMS detector
15-12-2008
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 »
 
Successful intermediate test for the future Neurospin magnet
03-11-2008
The 11.75 tonne whole body Iseult magnet to be installed in the Neurospin centre in 2012 will push back the boundaries of cerebral imaging. A key step in the success of this Franco-German project is the development of the SEHT test station in which a nominal field strength of 8 teslas was ... More »
 
The hidden shapes of atomic nuclei
18-06-2008
 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 »
 
Twelve lines for Antares
09-06-2008
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 »
 
Joint CDF, DZero effort lands Fermilab in Higgs territory
04-08-2008
Scientists from the CDF and DZero collaborations at the U.S. Department of Energy's Fermilab have combined Tevatron data from the two experiments to advance the quest for the long-sought Higgs boson. They have presented their results on August 3rd at the International Conference on High Energy ... More »
