Read article 'LHC delivers for the summer conferences'
With more luminosity delivered by the LHC between April and June 2012 than in the whole of 2011, the experiments had just what the collaborations wanted: as much data as possible before the summer con...
Read article '100 years of cosmic rays'
This issue of the CERN Courier marks the discovery of cosmic rays.
Read article 'A surprising asymmetry and more excited states'
The predictions in these channels suffer from relatively large theoretical uncertainties but these can be overcome by measuring asymmetries in which the uncertainties cancel.
Read article 'Seeing bosons in heavy-ion collisions'
Studies of heavy-ion collisions at the LHC are challenging and refining ideas on how to probe QCD – the theory of the strong interaction – at high temperature and density.
Read article 'EXO, MINOS and OPERA reveal new results'
The first results from the Enriched Xenon Observatory 200 (EXO-200) on the search for neutrinoless double beta decay show no evidence for this hypothesised process, which would shed new light on the n...

In a 40-day run ending on 22 May, the Institute of High-Energy Physics in China accumulated a total of 1.3 billion J/ψ events at the upgraded Beijing Electron Positron Collider (BEPCII) and Beijing ...
Read article 'The Milky Way’s dark-matter halo reappears'
Back in April, a study of the motion of hundreds of stars in the Milky Way found no evidence of a massive dark-matter halo (CERN Courier June 2012 p11). The finding came as a surprise and did not long...
Read article 'IceCube observations challenge ideas on cosmic-ray origins'
The IceCube collaboration, with a detector that looks at a cubic kilometre of ice at the South Pole, has searched for evidence of neutrinos associated with gamma-ray bursts (GRBs).
