Experiments Performed At COSY Accelerator Confirm Exotic Particle
2014-06-09 03:31:37

Forschungszentrum Jülich For decades, physicists have searched in vain for exotic bound states comprising more than three quarks. Experiments performed at Jülich’s accelerator COSY have now shown that, in fact, such complex particles do exist in nature. This discovery by the WASA-at-COSY collaboration has been published in the journal Physical Review Letters. The measurements confirm results from 2011, when the more than 120 scientists from eight countries discovered for the first...

Large Hadron Collider Picks Up Hint Of The Tetraquark
2014-04-13 05:21:58

redOrbit Staff & Wire Reports - Your Universe Online The Large Hadron Collider (LHC) has already played an essential role in the discovery of the so-called God particle, and now the world’s largest particle collider may have helped scientists discover a new form of matter known as the tetraquark. According to Maggie McKee of New Scientist, researchers conducting experiments at the LHC have confirmed the existence of a particle known as Z(4430). While physicists had previously...

Quarks In The Mirror

DOE/Thomas Jefferson National Accelerator Facility From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the building blocks of protons and neutrons, physicists have been exploiting those symmetries to study quarks' intrinsic properties and to uncover what those properties can reveal about the physical laws that govern them. A recent...

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...

CERN Particle Accelerator Reveals Previously Unknown Particle

It has not discovered the Higgs Boson -- not yet, anyway -- but the Large Hadron Collider (LHC) particle accelerator has revealed a never-before-discovered particle comprised of three quarks. The discovery, which was announced Friday by Symmetry Magazine, was made by University of Zurich physicists and was based on data gathered in the CMS detector at the Geneva, Switzerland-based facility, which is overseen by the European Organization for Nuclear Research (CERN). According to Symmetry...

Physicists at Mainz University significantly improve the calculation method for scattering experiments in particle physics Scientists at Johannes Gutenberg University Mainz (JGU) have set a new record for the calculation of scattering amplitudes. This kind of calculation is used to predict the outcome of accelerator experiments in which high-energy particles collide with one another. However, the calculations become increasingly difficult the greater the number of orders the physicists...

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...

Researchers use the NSF-supported Ranger supercomputer to explore alternative particle theories As the Large Hadron Collider (LHC) ramps up the rate and impact of its collisions, physicists hope to witness the emergence of the Higgs boson, an anticipated, but as-yet-unseen, fundamental particle that scientists believe gives mass to matter. The Higgs boson is a central component of the "standard model," a theory that defines the relationships between the forces of the universe. But, what if...

Physicists study rare particles to learn why the universe has more matter than antimatter Using data from experiments performed in 2010 at the Large Hadron Collider (LHC), the world's largest particle accelerator near Geneva, Switzerland, scientists are studying rare particle decays that could explain why the universe has more matter than antimatter. Led by Sheldon Stone, a physicist at Syracuse University, a group of scientists recently published their first observations of two different...

By David Salisbury, Vanderbilt University If the latest theory of Tom Weiler and Chui Man Ho is right, the Large Hadron Collider "“ the world's largest atom smasher that started regular operation last year "“ could be the first machine capable of causing matter to travel backwards in time. "Our theory is a long shot," admitted Weiler, who is a physics professor at Vanderbilt University, "but it doesn't violate any laws of physics or experimental constraints." One of the major...
