Read article 'ATLAS clocks rare decay of B mesons into muon pairs'
The decays of the B0s and B0 into muon pairs represent an important test of the Standard Model. Such decays take place through a flavour-changing neutral current process, which occurs only through loo...
Read article 'LHCb updates Bs oscillation measurement'
The LHCb experiment has recently made the most precise measurement yet of the asymmetry in oscillations between the matter and antimatter versions of Bs mesons. The measurement exploits the full LHCb ...
Read article 'ALICE separates hot and cold nuclear effects'
In the early stages of a high-energy collision, high-pT partons can be created, before producing sprays of hadrons that are measured experimentally as jets. Not only do high-pT partons carry informati...

The European Extremely Large Telescope (E-ELT) will be the largest optical/near-infrared telescope in the world.
Read article 'CERN experiment points to a cloudier pre-industrial climate'
New results reported in two papers in Nature from the CLOUD experiment at CERN imply that the pre-industrial climate may have had brighter and more extensive clouds than previously thought, sharpening...
Read article 'AWAKE sees first beam'
CERN’s pioneering AWAKE facility, which aims to drastically reduce the scale of particle accelerators, received its first beam on 16 June. The milestone signals the next stage of commissioning f...
Read article 'Neutron-star mergers create heaviest elements'
While core-collapse supernovae were thought to be the prime production site, a new study suggests that elements heavier than zinc originate from the merger of two neutron stars.

At the beginning of May, the LHC declared the start of a new physics season for its experiments. The “Stable Beams” visible on the LHC Page 1 screen (see image above) is the “go ahe...
Read article 'Short but intense…'
After a short, but intense, “intermezzo” as editor of the CERN Courier, I’m stepping down as I head off to new challenges. I would like to thank the CERN Courier Advisory Board and the m...
