CERN

The European Organization for Nuclear Research (French: Organisation européenne pour la recherche nucléaire), known as CERN; derived from the name Conseil européen pour la recherche nucléaire), is a European research organization that operates the largest particle physics laboratory in the world. Established in 1954, the organization is based in a northwest suburb of Geneva on the Franco–Swiss border and has 23 member states. Israel is the only non-European country granted full membership. CERN is an official United Nations Observer. The acronym CERN is also used to refer to the laboratory, which in 2016 had 2,500 scientific, technical, and administrative staff members, and hosted about 12,000 users. In the same year, CERN generated 49 petabytes of data. CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research – as a result, numerous experiments have been constructed at CERN through international collaborations. The main site at Meyrin hosts a large computing facility, which is primarily used to store and analyse data from experiments, as well as simulate events. Researchers need remote access to these facilities, so the lab has historically been a major wide area network hub. CERN is also the birthplace of the World Wide Web.

BASE demonstrates two-trap cooling

“In a significant technological advance for antimatter research, the BASE (Baryon Antibaryon Symmetry Experiment) collaboration has used laser-cooled ions to cool a proton more quickly and to lower temperatures than is possible using existing methods. The new technique, which introduces …

CERN to provide second DUNE cryostat

“The Laboratory deepens its collaboration with the US-based neutrino experiment with the provision of two enormous stainless-steel vessels for DUNE’s cutting-edge liquid-argon detectors Neutrinos are tricky beasts. Alone among known fundamental particles, they suffer from an identity crisis …

Twice the charm: long-lived exotic particle discovered

“Discovery of a new exotic hadron containing two charm quarks and an up and a down antiquark. Today, the LHCb experiment at CERN is presenting a new discovery at the European Physical Society Conference on High Energy Physics (EPS-HEP …

Tracking the rise of pixel detectors

“From their beginnings at CERN half a century ago, writes Chris Damerell, silicon pixel detectors for particle tracking have blossomed into a vast array of beautiful creations that have driven numerous discoveries, with no signs of the advances slowing down …

Searching for the unknown

“Count all the known kinds of particles in the universe. Now double it. This is the promise of a family of theoretical models known as Supersymmetry, or SUSY for short. The notion of theories predicting a doubling of observed particles …

LHCb observes four new tetraquarks

“The LHCb collaboration has added four new exotic particles to the growing list of hadrons discovered so far at the LHC. In a paper posted to the arXiv preprint server yesterday the collaboration reports the observation of two tetraquarks with …

AEgIS on track to test free-fall of antimatter

“The AEgIS collaboration at CERN’s Antiproton Decelerator (AD) has reported a milestone in its bid to measure the gravitational free-fall of antimatter – a fundamental test of the weak equivalence principle. Using a series of techniques developed in 2018, the …

CMS sets new bounds on the mass of leptoquarks

“The bounds are some of the tightest yet on the existence of third-generation leptoquarks At the most fundamental level, matter is made up of two types of particles: leptons, such as the electron, and quarks, which combine to form protons …

A transportable antiproton trap to unlock the secrets of antimatter

“The BASE collaboration is developing a transportable antiproton trap to make higher-precision measurements of the properties of antimatter The BASE collaboration at CERN has bagged more than one first in antimatter research. For example, it made the first ever more …

Higgs boson probes for new phenomena

“LHC physicists are on the hunt for many different forms of phenomena beyond the Standard Model. Some theories predict an as-yet undiscovered particle could be found in the form of a new resonance (a narrow peak) similar to the one …
