Nov 1, 2024 · Simulated colour-charge distributions in protons as Bjorken x decreases 10-2 to 10-6. Welcome to the digital edition of the January/February 2025 issue of CERN Courier.. Particle physicists are always doing things that have never been done before.

Jan 6, 2025 · CERN wishes you a happy 2025 as we look forward to a year of world-class research, uniting people from all over the world to push the frontiers of science and technology for the benefit of all. Welcome to the Quantum Year. The United Nations has declared 2025 as the International Year of Quantum Science and Technology, celebrating a century of research and innovation in the field.

Nov 25, 2024 · The particles completed a final lap of honour around the LHC on 23 November, bringing the 2024 run of the Large Hadron Collider (LHC) to a close. The LHC performed beautifully in its tenth year of operation. During the proton run, which began on 25 April and ended on 16 October, an exceptional volume of data was collected at a collision energy of 13.6 teraelectronvolts (TeV).

On Friday 5 April, at 6.25 p.m., the LHC Engineer-in-Charge at the CERN Control Centre (CCC) announced that stable beams were back in the Large Hadron Collider, marking the official start of the 2024 physics data-taking season. The third year of LHC Run 3 promises six months of 13.6 TeV proton collisions at an even higher luminosity than before, meaning more collisions for the experiments to ...

Dec 20, 2024 · 2024 holds special significance for CERN, as it celebrated its 70th anniversary. To mark this major milestone, the Organization held a series of public events in the CERN Science Gateway around the overarching themes: Unveiling the Universe, Exploring Farther: Machines for New Knowledge, Virtuous Circle of Knowledge and …

This image is taken from one of CERN's bubble chambers and shows the decay of a positive kaon in flight. The decay products of this kaon can be seen spiraling in the magnetic field of the chamber.

Oct 25, 2024 · Antimatter might sound like something out of science fiction, but at the CERN Antiproton Decelerator (AD), scientists produce and trap antiprotons every day. The BASE experiment can even contain them for more than a year—an impressive feat considering that antimatter and matter annihilate upon contact. The CERN AD hall is the only place in the world where scientists are able to store and ...

Oct 25, 2024 · At the Large Hadron Collider (LHC), heavy ions are accelerated to extremely high energies, which creates strong electromagnetic fields. As a result, photons from the oncoming lead-ion beams can interact with each other or with the nuclei; these interactions are known as ultraperipheral collisions. Photon–nucleus scatterings at the highest energy that can be achieved with existing particle ...

Sep 15, 2023 · Magnets, those everyday objects we stick to our fridges, all share a unique characteristic: they always have both a north and a south pole. Even if you tried breaking a magnet in half, the poles would not separate – you would only get two smaller dipole magnets. But what if a particle could have a single pole with a magnetic charge? For over a century, physicists have been searching for such ...

Feb 5, 2025 · CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the Universe is made of and how it works.
