The European Organization for Nuclear Research (French: Organisation européenne pour la recherche nucléaire), known as CERN ( /ˈsɜrn/; French pronunciation: [sɛʁn]; see History), is an international organization whose purpose is to operate the world's largest particle physics laboratory, which is situated in the northwest suburbs of Geneva on the Franco–Swiss border (46°14′3″N 6°3′19″E? / ?46.23417°N 6.05528°E? / 46.23417; 6.05528). Established in 1954, the organization has twenty European member states. The term CERN is also used to refer to the laboratory itself, which employs just under 2400 full-time employees, as well as some 7931 scientists and engineers representing 608 universities and research facilities and 113 nationalities. CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research. Numerous experiments have been constructed at CERN by international collaborations to make use of them. It is also the birthplace of the World Wide Web.
LHCb experiment observes new matter-antimatter difference
(Phys.org) —The LHCb collaboration at CERN today submitted a paper to Physical Review Letters on the first observation of matter-antimatter asymmetry in the decays of the particle known as the B0s. It is only the fourth sub-at ...
Large Hadron Collider experiments to present latest results at Moriond conference
Experiments at CERN's Large Hadron Collider (LHC) are set to present their latest results at the Moriond conference, which begins tomorrow in the Italian town of La Thuile, and runs until 16 March. Although all of the LHC ...
Free the quarks: Calculating the strong force
This year sees the 40th anniversary of the ground-breaking proposal that the interactions between quarks becomes weaker as they come closer together, laying the foundations of quantum chromodynamics, or QCD, the modern theory ...
Colliding different particle species: The LHC's proton-lead run
The new year brings a new type of collision at the LHC: the accelerator will smash protons and lead nuclei together, allowing CMS and the other LHC experiments to study the cold nuclear matter we expect these ...
Researchers observe new unexplained particle states
In the vast particle landscape, there are, to borrow a phrase, known knowns (the Standard Model, for example), unknown unknowns (exotic extensions of the Standard Model and beyond), and those ever-interesting ...
CMS observes melting of Upsilon particles in heavy-ion collisions
In 2011, CMS presented early evidence that Upsilon (Υ) particles produced in lead-lead collisions "melt" as a consequence of interacting with the hot nuclear matter created in these heavy-ion interaction ...
CMS, ATLAS experiments report Higgs-like particle close to the 7 sigma level
(Phys.org)—The latest research findings from the Large Hadron Collider (LHC) at CERN show that the CMS and ATLAS experiments are now reporting that the significance of their observation of the Higgs-like ...
The first LHC protons run ends with new milestone
(Phys.org)—This morning CERN completed the first LHC proton run. The remarkable first three-year run of the world's most powerful particle accelerator was crowned by a new performance milestone. The space between proton ...
Confining supersymmetry: LHCb presents evidence of rare B decay
Today, at the Hadron Collider Physics Symposium in Kyoto, the LHCb collaboration has presented the evidence of a very rare B decay, the rarest ever seen. The result further shrinks the region in which scientists ...
Precision measurements using top quarks at CMS
Amongst all known elementary particles, the top quark is peculiar: weighing as much as a Tungsten atom, it completes the so-called 3rd generation of quarks and is the only quark whose properties can be directly ...
Hunt for the platypus particle
All of the atoms in our bodies are made of electrons, protons and neutrons, and the protons and neutrons can be further broken down into quarks. Fundamentally, then, we are made of only two types of particles: ...
Proton-ion collisions: Behind the scenes of a hybrid interaction
Protons to the right, ions to the left: the basic principle of proton-ion collisions at the LHC might seem straightforward. However, this is an almost unprecedented mode of collider operation, certainly unique at the energy ...
Biochemistry: New technique to study interaction of metal ions in a liquid
In August, the members of an ISOLDE project called LOI88 successfully employed a new technique to study the interaction of metal ions in a liquid. It's the first time that specific ions have been studied ...
A challenging task: LHC collides protons with lead ions for first time
(Phys.org)—At 1.26am today the Large Hadron Collider (LHC) collided protons with lead ions for the first time.
Small but powerful: Fermilab develops magnets for the future High Luminosity LHC
Magnet size is crucial to an accelerator as it determines the final circumference and power. This spring, Fermilab unveiled a 10.4 Tesla magnet that is shorter than the 8 Tesla magnets currently installed ...
