October 2015 was a turning point for the High Luminosity LHC (HL-LHC) project, marking the end of the European-funded HiLumi LHC Design Study activities, and the transition to the construction phase, which is also reflected […]
Mars liquid-water flows You might already have seen this image in a newspaper or magazine. It illustrated NASA’s announcement on 28 September of liquid-water flows on Mars. The evidence comes from dark, narrow streaks on slopes appearing in the […]
The next-generation long-baseline neutrino-oscillation experiment is gaining global interest.
The light shining from high-energy collisions of heavy nuclei reveals unique information on quark–gluon plasma.
Beautiful images from the Atacama desert celebrate ALMA’s scientific achievements.
Two prominent scientists recall the work and personality of the Nobel laureate who was their mentor.
Del Rosso The CERN Courier is not exclusively CERN’s. Its subtitle “International Journal of High-Energy Physics” stands as a friendly warning to all those readers who might otherwise think it is an official mouthpiece of the CERN […]

Close orbit A pair of supermassive black holes (SMBHs) in close orbit around each other are expected to produce gravitational waves. The background “rumble” of gravitational waves resulting from many such systems in the universe should be […]
Attempts to produce a Harry Potter-style invisibility cloak have been improving, but they have so far tended to be too bulky to really compare to clothing. Now, Xingjie Ni of the University of California in […]
Measurements of cosmological distance are of great importance, and any new ways of obtaining information other than via redshift analyses would be very welcome. Kiyoshi Wesely Masui and Kris Sigurdson of the University of British […]
Test magnet High magnetic fields are the Holy Grail of high-energy accelerators. The strength of the dipole field determines the maximum energy the beam can achieve on a given orbit, and large-aperture, high-gradient quadrupoles, with high peak […]
Proton beams crossed inside each of the CMS and ATLAS detectors 20 million times a second during the 2012 LHC proton–proton run. However, the physics programme of CMS is based on only a small subset of […]
In high-energy hadron–hadron collisions, each incoming hadron behaves as a loosely bound system of massless partons – quarks, antiquarks and gluons. The interaction of incoming hadrons is described as the pair-wise interactions of partons from […]
Measurements of two-particle angular correlations in proton–proton (pp) collisions at the LHC have shown a feature commonly called the “ridge”: an enhancement in production of particle pairs at small azimuthal angle separation, Δφ, that extends […]
The ALICE experiment, designed for the LHC heavy-ion programme, is particularly well-suited for the detection and study of very high-energy cosmic events. The apparatus is located in a cavern 52 m underground, with 28 m of overburden […]
Le LHC haute luminosité va de l’avant Un nouveau record pour l’aimant RMC d’essai au CERN CMS : de nouveaux paramètres de déclenchement pour la recherche des résonances di-jet à faible masse LHCb mesure avec une précision inédite la section efficace de la double diffusion partonique ATLAS observe les anisotropies elliptiques à longue portée dans les collisions pp à √s = 13 et 2.76 TeV ALICE regarde le ciel (deuxième partie) Le venin d’une guêpe à l’assaut du cancer Onze années de recherche et toujours aucune trace d’ondes gravitationnelles
New hope for cancer treatment If you have an aversion to wasps, it might help to know that the venom from one of them, Polybia paulista, offers new hope for cancer treatment. Natália Bueno Leite of São Paolo State University […]
Carbon atoms deposited on graphene via focussed electron-beam-induced deposition (FEBD), making patterns that change with time, enable the creation of circuits that do something one day and something else the next. Songkil Kim of the […]
In quantum mechanics, you can put an object into a superposition of states for “here” and “there”, but we never seem to see those. And we say that there is decoherence, but what causes it? […]
Two years on Tunnelling machine Almost two years ago, CERN Council approved the “Programme for the Construction and Bringing into Operation of the CERN 300 GeV Laboratory”. The SPS [Super Proton Synchrotron] project has now reached the stage […]
