ATLAS Collaboration Detects Process Even Rarer Than Higgs Particle

July 17, 2014

1 Comment

A new published study from the ATLAS Collaboration reports the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles. Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world’s largest and most powerful “atom smasher,” […]

New CERN Research Details Evidence of the Direct Decay of the Higgs Boson to Fermions

June 24, 2014

0 Comments

New research published in Nature Physics details strong evidence of the direct decay of the Higgs boson to fermions. If evidence of the Higgs boson revealed two years ago was the smoking gun, particle physicists at Rice University and their colleagues have now found a few of the bullets. The European Organization for Nuclear Research […]

A Path Toward a New Breed of Miniature Particle Accelerators

May 30, 2014

0 Comments

Berkley Lab researchers show how beams of various colors and phases affect plasma, finding that laser light needn’t be as precise as previously thought to drive miniature particle accelerators. Making a tabletop particle accelerator just got easier. A new study shows that certain requirements for the lasers used in an emerging type of small-area particle […]

Physicists Confirm Discovery of Four-Quark Hadron

April 14, 2014

1 Comment

The Large Hadron Collider beauty collaboration has confirmed the existence of exotic hadron with two quarks, two anti-quarks. Physicists in Syracuse University’s College of Arts and Sciences have helped confirm the existence of exotic hadrons — a type of matter that cannot be classified within the traditional quark model. Their finding is the subject of […]

High-Precision Measurement of the Electron is More Precise by a Factor of 13

February 28, 2014

0 Comments

Physicists from the Max Planck Institute have achieved a high-precision measurement of the atomic mass of the electron, 13 times more precise than previously known. Electrons are the quantum glue of our world. Without electrons there would be no chemistry, and light would be unable to interact with matter. If electrons were only a little […]

Astronomers Accurately Measure the Mass of Neutrinos for the First Time

February 10, 2014

2 Comments

Astronomers from the universities of Nottingham and Manchester have accurately measured the mass of neutrinos for the first time. Scientists have solved a major problem with the current standard model of cosmology by combining results from the Planck spacecraft and measurements of gravitational lensing to deduce the mass of ghostly sub-atomic particles called neutrinos. The […]

LUX Dark Matter Detector Completes First 90-Days of Operation

October 31, 2013

2 Comments

With its first 90-days of operation completed, researchers at the Large Underground Xenon experiment are reporting that LUX has demonstrated a sensitivity that is better than any previous experiment looking to detect dark matter particles directly. Providence, Rhode Island (Brown University) — In its first three months of operation, the Large Underground Xenon (LUX) experiment […]

Physicists Develop a New Method to Accelerate Charged Particles

October 9, 2013

1 Comment

Physicists at the Max Planck Institute have developed a new method that uses light to accelerate charged particles, leading the way for more compact particle accelerators. Modern particle accelerators measure up to several kilometers in size and cost billions of euros. But thanks to a new method they could shrink to less than 10 meters […]

Scientists Use Partial Covariance Mapping to Probe Electron Dynamics

October 2, 2013

0 Comments

Using a technique called partial covariance mapping, scientists gain new insight into the dynamics of “hollow atom” formation. In a detailed study of how intense light strips electrons from atoms, researchers used an X-ray laser, SLAC’s Linac Coherent Light Source (LCLS), to measure and sort the ejected electrons and discover how this process takes place. […]

Physicists Create Coherent Beams of Twisted Light

September 19, 2013

1 Comment

By using a beam of electrons, a team of accelerator physicists has found a new method to create coherent beams of twisted light. Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate […]
