Has The LHC Created A New Form Of Matter?
2012-11-28 13:02:35

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In September 2012, the Large Hadron Collider (LHC) conducted a short run of collisions between protons and lead nuclei. The roughly two million events recorded were set to serve as a baseline for lead-lead collisions anticipated for next year. However, these events produced an unexpected result. Ridge Correlations Very high-energy particle collisions produce thousands of new particles which stream away from the...

Particle Collider To Become Accurate Stopwatch

Alan McStravick for redOrbit.com - Your Universe Online Just outside of Geneva, Switzerland is one of the world´s foremost ongoing experiments to explore not only the smallest components of our universe, but, in so doing, to understand the vastness of space, our universe as a whole, and just how it came into being. The Large Hadron Collider (LHC) at CERN is an approximately 17-mile-long ring buried some 330 feet underground which spans the border between Switzerland and France. The...

RHIC Atom Smasher Reveals First Hints Of Phase Boundary

April Flowers for redOrbit.com - Your Universe Online Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have observed the first glimpses of a possible boundary separating ordinary nuclear matter, made up of protons and neutrons, from the seething soup of their constituent quarks and gluons using the versatility and new capabilities of the Relativistic Heavy Ion Collider (RHIC). A quark-gluon plasma (QGP) exists at extremely high temperatures or density,...

Experiments At Large Hadron Collider Offer Better Understanding Of Primordial Universe
2012-08-14 09:25:13

Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists working at CERN´s Large Hadron Collider are gaining a better understanding of the primordial universe through experimentation involving the use of heavy ions. The collaborations between the ALICE, ATLAS and CMS projects have made new measurements of the kind of matter that most likely existed during the creation of the universe more than 13 billion years ago. Results of their experiments will be presented at the...

Record Setting 7.2 Trillion Degrees Fahrenheit In New York

[ Watch the Video ] Lee Rannals for redOrbit.com As record-setting heat and wildfires continue to consume Colorado, one team of scientists has created a temperature so hot the Sun would melt. Scientists working with a giant atom smasher at New York's Brookhaven National Laboratory have created the hottest temperature ever seen on Earth, at 7.2 trillion degrees Fahrenheit. The excruciatingly hot temperature has been verified by the Guinness Book of Records, and confirmed as...

Previous theories imposed a limit on how 'liquid' fluids can be -- but new calculations show that quark-gluon-plasma in high-energy particle accelerators can be even have a lower viscosity than this limit suggests How liquid can a fluid be? This is a question particle physicists at the Vienna University of Technology have been working on. The "most perfect liquid" is nothing like water, but the extremely hot quark-gluon-plasma which is produced in heavy-ion collisions at the Large Hadron...

Large Hadron Collider Set To Investigate Big Bang With More Precision
2011-11-02 10:08:31

Researchers at Switzerland´s Large Hadron Collider (LHC) are setting aside four weeks to investigate the conditions of the early universe in more detail than ever before and taking a break from searching for the Higgs boson, David Shiga from New Scientist is reporting. The Higgs boson experiment has produced roughly 6 inverse femtobarns of collision data, about three times the total used in the last major analysis searching for the elusive particle, thought to endow other particles...

By comparing theory with data from STAR, Berkeley Lab scientists and their colleagues map phase changes in the quark-gluon plasma In its infancy, when the universe was a few millionths of a second old, the elemental constituents of matter moved freely in a hot, dense soup of quarks and gluons. As the universe expanded, this quark"“gluon plasma quickly cooled, and protons and neutrons and other forms of normal matter "froze out": the quarks became bound together by the exchange of...

Directors of the CERN research center said that new data on the origins of the universe is pouring in so quickly that physicists may extend the current opening phase of their "Big Bang" project to the end of 2012. An extension could lead to an early discovery of the elusive Higgs boson, which is believed to have turned an amorphous mass of particles into solid matter at the birth of the universe. "There is a big window for new discoveries opening up and we want to ensure the momentum of...

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...
