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...

Once regarded as the stuff of science fiction, antimatter"”the mirror image of the ordinary matter in our observable universe"”is now the focus of laboratory studies around the world. While physicists routinely produce antimatter with radioisotopes and particle colliders, cooling these antiparticles and containing them for any length of time is another story. Once antimatter comes into contact with ordinary matter it "annihilates""”or disappears in a flash of gamma...

Researchers at RIKEN, Japan's flagship research institution, have successfully devised the world's first experimental technique for measuring ground-state hyperfine transitions of antihydrogen. By enabling scientists to test fundamental theories of symmetry and gravity, the new technique promises to shed light on some of the most profound mysteries of our universe. (PRWeb UK) December 6, 2010 New technique for antihydrogen synthesis promises answers to mysteries of antimatter Researchers...

PlanClear, the nuclear medicine industry's premier Growth Management firm, has finalized and issued its performance report for the 2010 3rd Qtr and (partial) 4th Qtr accomplishments of industry leader Positron (POSC). The PlanClear report highlighted the accomplishment of three critical benchmarks: 1) Sale of 15 PET Camera systems within one year after receiving FDA approval, 2) Eliminating debt and strengthening the POSC balance sheet, and 3) Successful R&D efforts resulting in a new...

Study refines predictions of what may constitute evidence of elusive particles Astrophysicists are looking everywhere "“ inside the Large Hadron Collider, in deep mines and far out into space "“ for evidence of dark matter, which makes up about 25 percent of the energy density of the universe. Despite the recent tantalizing observation of excess high-energy positrons "“ thought to be due to dark matter "“ UC Irvine researchers say we're not quite there yet. Models...

Recently, several astronomical experiments have revealed mysterious components of elementary particles. But up until now, the origin of electrons and positrons is unknown. Is dark matter the actual origin of this radiation, as some physicists speculate? Now an international team of astrophysicists, including the Bochum junior professor Dr. Julia Becker and the Dortmund physicist Prof. Dr. Dr. Wolfgang Rohde, have found a simple explanation: giant stars, at least fifteen times the mass of our...

A team of researchers working with data from ESA's Integral gamma-ray observatory has disproved theories that some form of dark matter explains mysterious radiation in the Milky Way. That this radiation exists has been known since the 1970s, and several theories have been proposed to explain it. Integral's unprecedented spectral and spatial resolution showed that it strongly peaks towards the center of the Galaxy, with an asymmetry along the Galactic disc. Several researchers have...

A team of astrophysicists has solved a mystery that led some scientists to speculate that the distribution of certain gamma rays in our Milky Way galaxy was evidence of a form of undetectable "dark matter" believed to make up much of the mass of the universe. In two separate scientific papers, the most recent of which appears in the July 10 issue of the journal Physical Review Letters, the astrophysicists show that this distribution of gamma rays can be explained by the way "antimatter...

Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma "jet." This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and...

Positron has acquired an exclusive license to a coronary disease reversal and prevention practice management program created by Lance Gould and the University of Texas Health Science Center at Houston. Joe Oliverio, president of Positron, said: "We are grateful to the University of Texas Health Science Center at Houston and Dr Gould for selecting Positron as the exclusive licensee of their heart disease management product. "The market is void of such a product and will position Positron...
