Berkeley Lab nuclear scientists join with their international colleagues in the latest record-breaking discovery at RHIC Eighteen examples of the heaviest antiparticle ever found, the nucleus of antihelium-4, have been made in the STAR experiment at RHIC, the Relativistic Heavy Ion Collider at the U.S. Department of Energy's Brookhaven National Laboratory. "The STAR experiment is uniquely capable of finding antihelium-4," says the STAR experiment's spokesperson, Nu Xu, of the Nuclear Science...

Direct measurements allow detailed look at how quarks of different flavors contribute to spin Scientists hoping to unravel the mystery of proton spin at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, have a new tool at their disposal "” the first to directly explore how quarks of different types, or "flavors," contribute to the overall spin of the proton. The technique,...

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...

Scientists working at the CERN research center in Geneva, Switzerland say their "Big Bang" project should show the first proof of the existence of dimensions beyond the four known -- length, width, height and time -- as early as next year. In the past eight months of results from experiments in the Large Hadron Collider (LHC), the scientists have gathered preliminary findings that could prove by the end of 2011 whether or not the mysterious Higgs boson really exists. A spokesman for one of...

Modern, compact ion injector will feed new kinds of particles to RHIC and NSRL A new source of ions will soon be the starting point for the beams entering two major research facilities at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory - the Relativistic Heavy Ion Collider (RHIC - http://www.bnl.gov/rhic), where physicists are recreating conditions of the early universe to learn more about the forces that hold matter together, and the NASA Space Radiation Laboratory...

A worldwide team of researchers, including 10 from Texas A&M University, have for the first time created a particle that is believed to have been in existence immediately after the creation of the universe "“ the so-called "Big Bang" "“ and it could lead to new questions and answers about some of the basic laws of physics because in essence, it creates a new form of matter. Researchers Carl Gagliardi, Saskia Mioduszewski, Robert Tribble, Matthew Cervantes, Rory Clarke, Martin...

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"...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
