Today, the LHCb experiment at CERN presented a measurement of the masses of two particular particles with a precision that is unprecedented at a hadron collider for this type of particles. Until now, the precise study of these "charmonium" particles, invaluable source of insights into the subatomic world, required dedicated experiments to be built.
[This post originally appeared in July 2012.] The big news this week is that the Large Hadron Collider, the massive particle accelerator at the European physics lab CERN, has apparently discovered the elusive and long-sought subatomic particle called the Higgs boson, which explains why other particles have mass. The hunt for the Higgs has consumed [Read More...]
In the shadow of the Large Hadron Collider, six teams are competing to answer one of the Universe’s deepest existential questions.
Your discussion on the mysteries of B meson particles refers to the 'B factories' where these are being studied (Nature546, 185–186;10.1038/546185b2017). Aside from CERN's Large Hadron Collider (LHCb) in Geneva, Switzerland, and Bel...
CBS's Zoo -- about a team of globe-trotting experts battling a catastrophic animal uprising and its aftermath -- might be the most insane show on network TV, and it's only gotten crazier in its current third season. Here are Zoo's most WTF moments... so far. More »
As the Large Hadron Collider (LHC) smashes protons at a centre-of-mass energy of 13 TeV, it creates a rich assortment of particles that are identified through the signature of their interactions with the ATLAS detector. But what if the...Show More Summary
Since resuming operation for Run 2, the Large Hadron Collider (LHC) has been producing about 20,000 Higgs bosons per day in its 13 TeV proton–proton collisions. At the end of 2015, the data collected by the ATLAS and CMS collaborations were already sufficient for new observations of the Higgs boson at the new collision energy. Show More Summary
Particle physics is rarely a cheap-and-easy endeavour. Just think about the Large Hadron Collider, buried deep beneath the Swiss-French border -- it cost over $16 billion to find the Higgs Boson. Well, today at 6.20AM AEST, America is breaking ground on another enormous particle physics experiment. More »
Very cool: Development on the LHC’s replacement is expected to take decades, which is why experts are keen to get started now. The aim is to put together a machine that’s some seven times more powerful than the hardware we have today. Show More Summary
This week, the Large Hadron Collider (LHC) was in technical stop, but particles continued to circulate in the other accelerators. This is because the chain of four injectors that feed the LHC also supplies particles to myriad experiments across several experimental areas.
On 29 June 2017, the CERN DC passed the milestone of 200 petabytes of data permanently archived in its tape libraries. Where do these data come from? Particles collide in the Large Hadron Collider (LHC) detectors approximately 1 billion times per second, generating about one petabyte of collision data per second. Show More Summary
Scientists at the Large Hadron Collider in Switzerland have discovered an exciting new particle -- or rather, an exciting combination of particles. It doesn't have quite the same impact that the Higgs Boson (the one people called the God Particle) did five years ago. Show More Summary
Researchers at the CERN Large Hadron Collider have discovered a doubly charming new particle, which has long been theorized to exist. Named ? cc ++ (Xi cc ++ ) (and no, we don't know how to pronounce it either), the particle is the first...Show More Summary
It's a big one.
Scientists at the Large Hadron Collider have detected a new kind of particle that may provide new insights into the "glue" of nature.
Scientists using the Large Hadron Collider have identified a form of particle that until now was only theoretical. Dubbed Xi-cc++, it’s the first double heavy particle, something that might help reveal more about how atoms hold together. Show More Summary
Today at the EPS Conference on High Energy Physics in Venice, the LHCb experiment at CERN's Large Hadron Collider has reported the observation of ?cc++ (Xicc++) a new particle containing two charm quarks and one up quark. The existence...Show More Summary
Scientists at the Large Hadron Collider have found the long-theorized particle, which is a type of baryon.
Scientists have found an extra-charming new subatomic particle they hope will help further explain a key force that binds matter together, reports the AP. Physicists at the Large Hadron Collider in Europe announced Thursday the fleeting discovery of a long theorized but never-before-seen type of baryon. Baryons are subatomic particles...
Researchers on the LHCb experiment at CERN's Large Hadron Collider have found a new particle, unlike any other seen yet, which could help study one of the universe's four fundamental forces
