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 optimised 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...

Two University of Colorado at Boulder physicists are part of a collaborative team working with the U.S. Department of Energy's Brookhaven National Laboratory in New York that have created the hottest temperature matter ever measured in the universe -- 7.2 trillion degrees Fahrenheit. The team used Brookhaven's giant atom smasher, the Relativistic Heavy Ion Collider, or RHIC, to ram charged gold particles into each other billions of times, creating a "quark-gluon plasma" with a temperature...

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory in New York report they have created the hottest temperature in the lab -- 4 trillion degrees Celsius -- which is thought to be consistent with actual temperatures that existed when the universe was born. The Relativistic Heavy Ion Collider (RHIC) was used to smash gold ions together to make super-heated explosions that lasted only milliseconds. RHIC is a particle accelerator that is 2.4 miles around and is buried...

Data suggest symmetry may 'melt' along with protons and neutrons Scientists at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy's Brookhaven National Laboratory, report the first hints of profound symmetry transformations in the hot soup of quarks, antiquarks, and gluons produced in RHIC's most energetic collisions. In particular, the new results, reported in the journal Physical Review Letters, suggest that "bubbles"...

Perimeter Institute Faculty member Jaume Gomis has won an Early Researcher Award from the Ministry of Research and Innovation (MRI) of Ontario. Early Researcher Awards help promising, recently-appointed Ontario researchers build their research teams of graduate students, postdoctoral fellows, research assistants and associates. The goal of the program is to improve Ontario's ability to attract and retain the best and brightest research talent. The $150,000 award will be used to support Dr....

Duke and Brookhaven examine free-flowing 'exploding cigars' Several years after Duke University researchers announced spectacular behavior of a low density ultracold gas cloud, researchers at Brookhaven National Laboratory have observed strikingly similar properties in a very hot and dense plasma "fluid" created to simulate conditions when the universe was about one millionths of a second old. The plasma was formed at a colossal 2 million degrees Kelvin temperatures within Brookhaven's...

British poet William Blake once wrote that a world was contained in a grain of sand. Physicists have done one better, finding a surprising link between streams of flowing sand grains and the birth of the universe. A new study in the latest issue of the journal Physical Review Letters finds that flowing sand grains show liquid-like behavior also witnessed in particle-collider experiments that simulate our universe's first moments. "Nature plays the tricks that it...

Using high-speed collisions between gold atoms, scientists think they have re-created one of the most mysterious forms of matter in the universe -- quark-gluon plasma. This form of matter was present during the first microsecond of the Big Bang and may still exist at the cores of dense, distant stars. UC Davis physics professor Daniel Cebra is one of 543 collaborators on the research. His main role was building the electronic listening devices that collect information about the collisions, a...
