After less than three weeks of heavy-ion running, the three experiments studying lead ion collisions at the LHC have already brought new insight into matter as it would have existed in the very first instants of the Universe's life. The ALICE experiment, which is optimized for the study of heavy ions, published two papers just a few days after the start of lead-ion running. Now, the first direct observation of a phenomenon known as jet quenching has been made by both the ATLAS and CMS...

The Large Hadron Collider (LHC) has taken new steps by smashing together lead ions instead of protons to create a "mini-Big Bang." Scientists working at the particle smasher achieved the feat on November 7. Experts working with the LHC created temperatures a million times hotter than the center of the sun. The LHC lies under the French-Swiss border near Geneva in a 16-mile long circular tunnel. The world's highest-energy particle accelerator has been colliding protons in search for the...

Researchers working at the world's highest-energy particle accelerator on the Franco-Swiss border are nearly set to create the Big Bang on a miniature scale. Since 2009, the Large Hadron Collider (LHC) has been smashing protons together, trying to shed light on the essential nature of matter. But for the upcoming experiments, planned for early November and running for four weeks, the team will have the accelerator collide lead ions instead. The collider, managed by the European...

Ground-breaking experiments in Switzerland question Universe's building blocks Researchers used Einstein's famous E=mc2 equation and the Large Hadron Collider to recreate a miniature version of the event at the origins of our Universe, and the first findings from their work were published in the journal Physical Review Letters. Dr. Andreas Warburton of McGill's Department of Physics made leading contributions to the analysis of data from the experiment, known as "ATLAS," meaning the findings...

A group of University of Toronto high-energy physicists, along with their 3,000 ATLAS colleagues, announced they have broken world records in the search for new particles as the first findings from the Large Hadron Collider (LHC) were presented July 26 in Paris, France. The first results, following only three months of successful operation of the LHC, have "re-discovered" some of the familiar particles that lie at the heart of the Standard Model of physics.  The Standard Model theory has...

First results from the LHC at CERN* are being revealed at ICHEP, the world's largest international conference on particle physics, which has attracted more than 1000 participants to its venue in Paris. The spokespersons of the four major experiments at the LHC "“ ALICE, ATLAS, CMS and LHCb "“ are today presenting measurements from the first three months of successful LHC operation at 3.5 TeV per beam, an energy three and a half times higher than previously achieved at a particle...

The Large Hadron Collider (LHC) is giving physicists hopeful candidates in the hunt for the heaviest elementary particle known to science. According to BBC News, so far their observations have been leading them in that direction. If the observations can be confirmed, it would be a first for Europe as the top quark particle has only been generated in one lab in the US. Dr Arnaud Lucotte, from the French National Centre of Scientific Research (CNRS), said the discovery could help physicists...

Scientists working with the Large Hadron Collider (LHC) said they have moved a step closer to reaching their goal of unlocking the mysteries of the Universe. The LHC has produced a record-breaking particle collision rate, which is about double the previous rate. According to physicist Andrei Golutvin, the collider is now generating about 10,000 particle collisions per second. The LHC is the world's highest-energy particle accelerator and is located in a 16 mile tunnel under the...

Scientists have simulated what is thought to be the sounds made by sub-atomic particles when they are produced at the Large Hadron Collider. Their goal is to develop a way for physicists at CERN to "listen to the data" and pick out the Higgs particle if and when they finally detect it. Lily Asquith modeled data from the giant Atlas experiment at the LHC. She worked with sound engineers to convert data taken during collisions at the LHC. "If the energy is close to you, you will hear a low...

A new high-speed integrated circuit to reliably transmit data in the demanding environment of the world's largest physics experiment is the fastest of its kind. This new "link-on-chip" "” or LOC serializer circuit "” was designed by physicists at Southern Methodist University in Dallas as a component for use in a key experiment of the Large Hadron Collider particle accelerator in Europe. The miniscule SMU LOC serializer was designed for ATLAS, which is the largest particle...

Word of the Day
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
