Latest Particle physics Stories
Scientists working at the US Tevatron particle collider near Batavia, Illinois on Wednesday said they have found the strongest evidence yet for the existence of the elusive “God particle.” They said their experiments mirror those from the Large Hadron Collider (LHC) in Europe that have narrowed the range where the Higgs boson particle could be hiding. The Higgs Boson is the missing link in the standard model of physics and is believed to be what gives objects mass, though scientists...
The world’s most precise measurement of the mass of the W boson, one of nature’s elementary particles, has been achieved by scientists from the CDF and DZero collaborations at the Department of Energy’s Fermi National Accelerator Laboratory. The new measurement is an important, independent constraint of the mass of the theorized Higgs boson. It also provides a rigorous test of the Standard Model that serves as the blueprint for our world, detailing the properties of the building blocks...
CERN physicists working at the Large Hadron Collider (LHC) near Geneva, Switzerland are to increase the machine’s energy output to embark on a last-ditch journey to find the elusive Higgs boson, a theoretical “God particle” that could change physics as we know it. Scientists say the 14 percent boost in the proton beams’ energies should improve the collider’s chances of finding “new physics” and definitively confirming or denying the existence of the Higgs boson. CERN will...

(OTC Bulletin Board: AXPW), the developer of advanced lead carbon PbC® batteries and energy storage systems, announced that as of February 3, 2012 it has completed a registered direct common stock offering providing gross proceeds of approximately $9.4 million. The shares sold, par value $0.0001, were priced at $0.35, which was the volume-weighted average price of the shares over a 40-day trading...
NEW CASTLE, Pa., Feb. 1 , 2012 /PRNewswire/ -- Axion Power International, Inc. (OTC Bulletin Board: AXPW) ("Axion" or "the Company"), the developer of advanced leadcarbon PbC® batteries and energy storage systems, today announced that it has entered into definitive agreements to sell an aggregate of not more than 28,571,429 shares of common stock, par value $0.0001 per share (the "Shares"), at a price per share of $0.35 for gross proceeds up to $10 million, before deducting...
A team of researchers from the University of California, Riverside (UCR) say they are close to determining whether or not anti-matter exerts a sort of "anti-gravity" in much the same what that ordinary matter exerts regular gravity. In an article published Friday, BBC News reports that, while it is well known that normal matter attracts all other matter in the universe, scientists currently do not know if anti-matter would attract other matter, or repel it. A trio of UCR experts may...
Lab scientists and international collaborators have created the shortest, purest X-ray laser pulses ever achieved, fulfilling a 45-year-old prediction and ultimately opening the door to new medicines, devices and materials. The researchers, reporting today (Jan. 26) in Nature, aimed radiation from the Linac Coherent Light Source (LCLS), located at the Stanford Linear Accelerator Center (SLAC), at a cell containing neon gas, setting off an avalanche of X-ray emissions to create a new...
UC Riverside physicists have launched a lab experiment to find out the answer Does antimatter behave differently in gravity than matter? Physicists at the University of California, Riverside have set out to determine the answer. Should they find it, it could explain why the universe seems to have no antimatter and why it is expanding at an ever increasing rate. In the lab, the researchers took the first step towards measuring the free fall of "positronium" – a bound state between a...
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...
Study represents step toward unified theory for quantum phase transformation New evidence this week supports a theory developed five years ago at Rice University to explain the electrical properties of several classes of materials -- including unconventional superconductors -- that have long vexed physicists. The findings in this week's issue of Nature Materials uphold a theory first offered in 2006 by physicist Qimiao Si, Rice's Harry C. and Olga K. Wiess Professor of Physics and...

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...
Physics is the scientific study of matter and its motion through space/time and its derivitives, including energy and force. It is generally the analysis of nature and is conducted to help us understand how the universe behaves. Physics comes from the Greek word physis, meaning "nature". It is among the oldest academic disciplines, and perhaps the oldest pertaining to astronomy. Physics has been considered synonymous with philosophy, chemistry, mathematics, and biology for more than 2000...
WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....
Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...
Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...
