In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. This is one of two elementary particles that mediate the weak interaction – one of the forces that govern the behaviour of matter in our universe. Show More Summary
A lot of people were recently reaching Sciencebase using the search phrase “LHC short primer”. I assume they’re after information about the Large Hadron Collider. So here’s a quick executive summary: The Large Hadron Collider (LHC) is...Show More Summary
In a 17-mile circular tunnel underneath the border between France and Switzerland, an international collaboration of scientists runs experiments using the world's most advanced scientific instrument, the Large Hadron Collider (LHC).Show More Summary
(University of Kansas) A team of high-energy experimental particle physicists, including several from the University of Kansas, has uncovered possible evidence of a subatomic quasiparticle dubbed an "odderon" that had only been theorized to exist.
It’s that time of year again when we look back at some of the news stories we’ve covered in 2017 and update you on later developments. Turning to July, staff at the Large Hadron Collider discovered the first “double heavy particle”.Show More Summary
The CMS Collaboration at CERN have just made public around half of the data collected in 2012 by the CMS detector at the Large Hadron Collider. This release includes sets used to discover the Higgs boson, and is being shared through the CERN Open Data portal.
In the Large Hadron Collider, protons become new particles, which become energy and light, which become data.
Highly localised research infrastructure investment, such as in the Large Hadron Collider, often leads to major scientific breakthroughs, but there is little evidence on the longer-term and wider geographical impacts on scientific output. Show More Summary
It's the end of the road for the protons this year after a magnificent performance from the Large Hadron Collider (LHC). On Friday, the final beams of the 2017 proton run circulated in the LHC. The run ended, as it does every year, with...Show More Summary
Watch this month's Perimeter Public Lecture—fascinating science brought to the masses—with Pauline Gagnon on Nov. 8 at 7 PM ET The post Perimeter Public Lecture: How ‘useless’ science led to the Large Hadron Collider appeared first on Macleans.ca.
Nobel Prize winner Frank Wilczek was optimistic back in 2012. After all, he'd just won a wager after scientists had just announced their Higgs boson discovery at the Large Hadron Collider particle physics experiment in Switzerland. He made another bet - but he's doesn't feel as confident today. More »
Today, CERN Control Centre operators announced good news, the Large Hadron Collider (LHC) has successfully met its production target for 2017, delivering more than 45 inverse femtobarns to the experiments.
Collisions of lead nuclei in the Large Hadron Collider (LHC) take place at such great energies that quarks that are normally confined inside nucleons are released and, together with the gluons that hold them together, form an exotic quark-gluon plasma. Show More Summary
(The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences) Collisions of lead nuclei in the Large Hadron Collider (LHC) particle accelerator take place at such great energies that quarks that are normally confined...Show More Summary
Today, the LHC is getting a taste of something unusual. For eight hours, the Large Hadron Collider is accelerating and colliding xenon nuclei, allowing the large LHC experiments, ATLAS, ALICE, CMS and LHCb, to record xenon collisions for the first time.
The Large Hadron Collider at CERN in Switzerland, the largest accelerator in the world, has a circumference of around 26 kilometres. Researchers at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU), Germany, are attempting to go to the other extreme by building the world's smallest accelerator—one that fits on a microchip.

Top quarks in the Large Hadron Collider (LHC) proton-proton collisions are predominantly produced in pairs, with one top quark and one top antiquark. In order to measure the production rates of top quark pairs, the ATLAS Experiment examined events with an electron, muon, and one or two jets that were likely to have originated from bottom quarks.

In November of 2014, in a first, unexpected move for the field of particle physics, the Compact Muon Solenoid (CMS) experiment—one of the main detectors in the world's largest particle accelerator, the Large Hadron Collider—released to the public an immense amount of data, through a website called the CERN Open Data Portal.
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.
